+/**
+The CEZDecompressor class provides in-memory de-compression functions, including integrity checks of the compressed data.
+This version of the library supports only one compression / de-compression method (deflation / inflation).  De-compression
+can be done in a single step (using DecompressL()) if the buffers are large enough (for example if an input file is mmap'ed),
+or can be done by repeated calls of the InflateL() function.  The source data is de-compressed to the target buffer (both source 
+and target contained within the buffer manager argument).
+
+Note: In this version of the library a windowBits value of 8 is unsupported due to a problem with the window size being 
+set to 256 bytes. Although a value of 8 will be accepted by the CEZCompressor constructors, as it is being changed 
+internally by Zlib from 8 to 9, it will not be possible to use the same value for decompression. This is because the 
+Zlib functions called by the CEZDecompressor constructors do not make the same change internally and as a result a 
+KEZlibErrData is returned when calling InflateL(). It is therefore advised that for this version of the library 
+windowBits of 9 is used in place of 8.
