    The code is organized in three 'steps' corresponding to the PR, ME, and MC functions. The output from
    the PR step is buffered in a 'circular' buffer, and similarly the ME output is put in a circular buffer. 
    
    The implementation is done in steps, emulating what can be done in firmware. One each step we do:
    
    1) A projection is read and if there is space it is insert into the inputProjBuffer_
    
    2) Process next match in the ME - if there is an idle ME the next projection is inserted
    
    3) Readout match from ME and send to match calculator
