Collect an assignment from the nbgrader exchange

Options
=======
The options below are convenience aliases to configurable class-options,
as listed in the "Equivalent to" description-line of the aliases.
To see all configurable class-options for some <cmd>, use:
    <cmd> --help-all

--debug
    set log level to DEBUG (maximize logging output)
    Equivalent to: [--Application.log_level=DEBUG]
--quiet
    set log level to CRITICAL (minimize logging output)
    Equivalent to: [--Application.log_level=CRITICAL]
--update
    Update existing submissions with ones that have newer timestamps.
    Equivalent to: [--ExchangeCollect.update=True]
--before-duedate
    Collect the last submission before due date or the last submission if no submission before due date.
    Equivalent to: [--ExchangeCollect.before_duedate=True]
--log-level=<Enum>
    Set the log level by value or name.
    Choices: any of [0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL']
    Default: 30
    Equivalent to: [--Application.log_level]
--student=<Unicode>
    File glob to match student IDs. This can be changed to filter by student.
    Note: this is always changed to '.' when running `nbgrader assign`, as the
    assign step doesn't have any student ID associated with it. With `nbgrader
    submit`, this instead forces the use of an alternative student ID for the
    submission. See `nbgrader submit --help`.
    If the ID is purely numeric and you are passing it as a flag on the command
    line, you will need to escape the quotes in order to have it detected as a
    string, for example `--student=""12345""`. See:
        https://github.com/jupyter/nbgrader/issues/743
    for more details.
    Default: '*'
    Equivalent to: [--CourseDirectory.student_id]
--assignment=<Unicode>
    The assignment name. This MUST be specified, either by setting the config
    option, passing an argument on the command line, or using the --assignment
    option on the command line.
    Default: ''
    Equivalent to: [--CourseDirectory.assignment_id]
--notebook=<Unicode>
    File glob to match notebook names, excluding the '.ipynb' extension. This
    can be changed to filter by notebook.
    Default: '*'
    Equivalent to: [--CourseDirectory.notebook_id]
--db=<Unicode>
    URL to the database. Defaults to sqlite:///<root>/gradebook.db, where <root>
    is another configurable variable.
    Default: ''
    Equivalent to: [--CourseDirectory.db_url]
--course-dir=<Unicode>
    The root directory for the course files (that includes the `source`,
    `release`, `submitted`, `autograded`, etc. directories). Defaults to the
    current working directory.
    Default: ''
    Equivalent to: [--CourseDirectory.root]
--timezone=<Unicode>
    Timezone for recording timestamps
    Default: 'UTC'
    Equivalent to: [--Exchange.timezone]
--course=<Unicode>
    A key that is unique per instructor and course. This can be specified,
    either by setting the config option, or using the --course option on the
    command line.
    Default: ''
    Equivalent to: [--CourseDirectory.course_id]

Class options
=============
The command-line option below sets the respective configurable class-parameter:
    --Class.parameter=value
This line is evaluated in Python, so simple expressions are allowed.
For instance, to set `C.a=[0,1,2]`, you may type this:
    --C.a='range(3)'

Application(SingletonConfigurable) options
------------------------------------------

    Configure additional log handlers.
    The default stderr logs handler is configured by the log_level, log_datefmt
    and log_format settings.
    This configuration can be used to configure additional handlers (e.g. to
    output the log to a file) or for finer control over the default handlers.

    * A logging handler that writes to stderr called
      ``console`` which uses the formatter ``console``.
    * A logger with the name of this application set to ``DEBUG``
      level.

    ) by default.  This should only be used if you carefully set the primary
    groups of your notebook servers and fully understand the unix permission
    model.  This changes the default permissions from 444 (unwriteable) to 664
    (writeable), so that other instructors are able to delete/overwrite files.
    Default: False

    List of file names or file globs. Upon copying directories recursively,
    matching files and directories will be ignored with a debug message.
    Default: ['.ipynb_checkpoints', '*.pyc', '__pycache__', 'feedback']
--CourseDirectory.include=<list-item-1>...
    List of file names or file globs. Upon copying directories recursively, non
    matching files will be ignored with a debug message.
    Default: ['*']

    variable in the `directory_structure` config option.
    Default: 'release'
--CourseDirectory.root=<Unicode>
    The root directory for the course files (that includes the `source`,
    `release`, `submitted`, `autograded`, etc. directories). Defaults to the
    current working directory.
    Default: ''
--CourseDirectory.solution_directory=<Unicode>
    The name of the directory that contains the assignment solution after
    grading has been completed. This corresponds to the `nbgrader_step` variable

    The name of the directory that contains the master/instructor version of
    assignments. This corresponds to the `nbgrader_step` variable in the
    `directory_structure` config option.
    Default: 'source'
--CourseDirectory.source_with_tests_directory=<Unicode>
    The name of the directory that contains notebooks with both solutions and
    instantiated test code (i.e., all AUTOTEST directives are removed and
    replaced by actual test code). This corresponds to the `nbgrader_step`
    variable in the `directory_structure` config option.
    Default: 'source_with_tests'
--CourseDirectory.student_id=<Unicode>
    File glob to match student IDs. This can be changed to filter by student.
    Note: this is always changed to '.' when running `nbgrader assign`, as the
    assign step doesn't have any student ID associated with it. With `nbgrader
    submit`, this instead forces the use of an alternative student ID for the
    submission. See `nbgrader submit --help`.
    If the ID is purely numeric and you are passing it as a flag on the command
    line, you will need to escape the quotes in order to have it detected as a
    string, for example `--student=""12345""`. See:
        https://github.com/jupyter/nbgrader/issues/743
    for more details.
    Default: '*'
--CourseDirectory.student_id_exclude=<Unicode>
    Comma-separated list of student IDs to exclude.  Counterpart of student_id.

--CourseDirectory.submitted_directory=<Unicode>
    The name of the directory that contains assignments that have been submitted
    by students for grading. This corresponds to the `nbgrader_step` variable in
    the `directory_structure` config option.

Examples
--------

    Collect assignments students have submitted. For the usage of instructors.

            This command is run from the top-level nbgrader folder. Before running
            this command, you may want toset the unique `course_id` for the course.
            It must be unique for each instructor/course combination. To set it in
            the config file add a line to the `nbgrader_config.py` file:

                c.CourseDirectory.course_id = 'phys101'

            To pass the `course_id` at the command line, add `--course=phys101` to any
            of the below commands.

            To collect `assignment1` for all students:

                nbgrader collect assignment1

            To collect `assignment1` for only `student1`:

                nbgrader collect --student=student1 assignment1

            Collected assignments will go into the `submitted` folder with the proper
            directory structure to start grading. All submissions are timestamped and
            students can turn an assignment in multiple times. The `collect` command
            will always get the most recent submission from each student, but it will
            never overwrite an existing submission unless you provide the `--update`
            flag:

                nbgrader collect --update assignment1
