TPRegexp
========

1. Modularized Match() and Substitute() functions so that the low-level work
   is done by MatchInternal() and SubstituteInternal().

2. Added function TString GetModifiers() that translates from bit-flag
   options back to perl-style option characters.

3. For all functions that do actual matching replaced the default value
   of 'Int_t nMatchMax' argument from 30 to 10. PCRE internals require
   the index buffer to be 3-times the number of allowed matches. This
   multiplication is now performed in individual functions and nMatchMax
   is really the number of allowed matches. Two function calls in 
   TString passing this number explicitly have been updated.

TPMERegexp
==========

New sub-class of TPRegexp with API closer to PERL.
Supports main Perl operations using regular expressions (Match,
Substitute and Split). To retrieve the results one can simply use
operator[] returning a TString.
