0.0.1  Complete rework to mostly use macros instead of
       opcodes defined in rx.ops. Reason why I dropped
       previous history.

       Support of literal match, sequences, \d D * *? 

       To correct: for test purpose now no longer relevant, when
       parsing a rx, a literal match is limited to one char.
       Various bug to identify and fix but the infrastructure to
       weave basic opcodes sounds mostly sane

0.0.2  corrected: .*? was completely wrong, .* backtracking was
       incomplete, search was proceeding past end of string.
       Some tests are still wrong.


0.0.3 added an AUTOLOAD for the Rx::.*_ep
      Some added and updated doc.
      added incrementation of generated imcc for inner expression
      Some tests are still wrong.
