/*
 * Most of the protocols have a header consisting of a mark/space of a particular length followed by 
 * a series of variable length mark/space signals.  Depending on the protocol they very the lengths of the 
 * mark or the space to indicate a data bit of "0" or "1". Most also end with a stop bit of "1".
 * The basic structure of the sending and decoding these protocols led to lots of redundant code. 
 * Therefore I have implemented generic sending and decoding routines. You just need to pass a bunch of customized 
 * parameters and it does the work. This reduces compiled code size with only minor speed degradation. 
 * You may be able to implement additional protocols by simply passing the proper values to these generic routines.
 * The decoding routines do not encode stop bits. So you have to tell this routine whether or not to send one.
