RunLength encoder class.
Library: xviews or winviews or mviews (mutually exclusive)
This class allows you to encode binary data to data in a run length encoded binary description. NOT YET IMPLEMENTED, just writes runs of 1. The generated data is a sequence of runs, each run consists of a length
byte followed by 1 to 127 bytes of data. If the length
byte is in the range 0 to 127, the following lenght
+ 1 byte (1 to 128 bytes) are to be copied literally upon decompression. if length
is in the range 129 to 255, the following single byte is to be replicated 257 - length
(2 to 128 times) upon decompression.
