Upload Progress Monitor

This is a WSGI middleware component which monitors the status of files
being uploaded.  It includes a small query application which will return
a list of all files being uploaded by particular session/user.

    monitors and reports on the status of uploads in progress

Parameters:

``application``

This is the next application in the WSGI stack.

``threshold``

This is the size in bytes that is needed for the
            upload to be included in the monitor.

``timeout``

This is the amount of time (in seconds) that a upload
            remains in the monitor after it has finished.

Methods:

``uploads()``

This returns a list of ``environ`` dict objects for each
            upload being currently monitored, or finished but whose time
            has not yet expired.

For each request ``environ`` that is monitored, there are several
    variables that are stored:

``paste.bytes_received``

This is the total number of bytes received for the given
            request; it can be compared with ``CONTENT_LENGTH`` to
            build a percentage complete.  This is an integer value.

``paste.request_started``

This is the time (in seconds) when the request was started
            as obtained from ``time.time()``.  One would want to format
            this for presentation to the user, if necessary.

``paste.request_finished``

This is the time (in seconds) when the request was finished,
            canceled, or otherwise disconnected.  This is None while
            the given upload is still in-progress.

TODO: turn monitor into a queue and purge queue of finished
          requests that have passed the timeout period.

    reports on the progress of uploads for a given user

This reporter returns a JSON file (for use in AJAX) listing the

    uses the ``REMOTE_USER`` environment to compare between the current
    request and uploads in-progress.  If they match, then a response
    record is formed.

``match()``

This member function can be overriden to provide alternative
            matching criteria.  It takes two environments, the first
            is the current request, the second is a current upload.

``report()``

This member function takes an environment and builds a
            ``dict`` that will be used to create a JSON mapping for
            the given upload.  By default, this just includes the
            percent complete and the request url.
