+/**
+The CEZCompressor class provides in-memory compression functions, including integrity checks of the uncompressed data.
+This version of the library supports only one compression method (deflation).  Compression can be done in a single step
+(using CompressL()) if the buffers are large enough (for example if an input file is mmap'ed), or can be done by repeated calls
+of the DeflateL() function.  The source data is compressed to the target buffer (both source and target contained within 
+the buffer manager argument), and various other arguments distinguish the different compression settings.
