-/**
-A collection class that loads data from pack files.  As opposed to plain
-collection files, pack files are composed from a number of logical files.  They
-also contain a directory with a list of objects contained in the pack and which
-logical files they are in.  This allows the pack to be loaded in a piecewise
-manner instead of all at once.
-
-It's possible for a pack file to contain plain collection files as well.  When
-an object from such a file is requested, the entire sub-collection it is stored
-in is loaded.
