Initial documentation for Model.
Added JSDoc for Backbone.Model class.
Added JSDoc for Collection and some option classes.
Added missing options sort and merge to AddOptions.
Added new CollectionSetOptions class to contain valid options for the Collection.set method.
Fixed error in declaration of Collection.drop() (and aliases tail and reduce). This always returns an array.
Made initialMemo argument of Collection.foldl optional (as it should be according to the documentation).
Added overload for Collection.indexOf accepting a start-index to start the search from.
Fixed erroneous declaration of Collection.initial(). This always returns an array.
Removed Collection.sortIndex, this method does not appear to exist on Backbone.Collection.
