+/**
+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).
