//
// Purpose:
//   The highest level of the filtering implementation. Abstracts the filter
//   away from the classes that access the file directly.
//   From highest level of abstraction of the file to lowest:
//      FilteredBaseData, BaseDataFile, LargeByteBuffer, VersatileMemoryPage
//
// Description:
//   [The set of functions, macros, etc. defined in the file]
