readAsMap: A collection taking key as a string that will be matched with regex against
	file types and the type to read as.  If no match is found, it will use readAsDefault.
	The default map is:
	{
		'image/*': 'DataURL',
		'text/*' : 'Text'
	}
readAsDefault: 'ArrayBuffer' | 'Text' | 'DataURL' (default)
accept: A regex string to match the contenttype of a given file.
		For example: 'image/*' to only accept images.
		on.skip will be called when a file does not match the filter.
dragClass: A CSS class to add onto the element called with setupDrop while dragging
on:
	loadstart: function(e, file) { }
	progress: function(e, file) { }
	load: function(e, file) { }
	abort: function(e, file) { }
	error: function(e, file) { }
	loadend: function(e, file) { }
	beforestart: function(file) { } Called before a file is passed to the FileReader.  Return false to prevent processing.  This is used along with the 'accept' parameter to skip a file (ex: an image is too big to process).  This wouldn't be needed, except that Chrome sometimes crashes when calling abort(): http://code.google.com/p/chromium/issues/detail?id=60979
	skip: function(file) { } Called only when a read has been skipped because of the accept string
	groupstart: function(group) { }
	groupend: function(group) { }

e - the native ProgressEvent created by the FileReader

file - an extension of the original File object.  See W3 link above for all native parameters.  Here are the extra fields

file.extra = {
	fileID: a generated int id for this file.
	groupID: the group that it belongs to
	nameNoExtension: 'myImage' instead of 'myImage.png'
	extension: 'png' instead of 'myImage.png'
	prettySize: '46.47' kb instead of 47585 (size field)
}

group: simple grouping of files.  Each time a change event or drop even happens and a FileList is created, and all of these files are stored inside a group object.

	groupID: a generated int id for this group
	files: the FileList associated with the group
	started: the Date the group was recieved as input
	ended: the Date all files in the group finished loading
