This class allows us to retrieve a specified number of bits from the input buffer, as well as copy big byte blocks. It uses an int buffer to store up to 31 bits for direct manipulation. This guarantees that we can get at least 16 bits, but we only need at most 15, so this is all safe. There are some optimizations in this class, for example, you must never peek more than 8 bits more than needed, and you must first peek bits before you may drop them. This is not a general purpose class but optimized for the behaviour of the Inflater. authors of the original java version : John Leuner, Jochen Hoenicke
