Simplification of code for regex testing

Streamlined code quite a bit after some suggestions.  Removed 20+
regular expression boolean functions and combined them into 2 generic
functions (one that ignores case and the other one doesnt ignore case).
By doing this, it is now much easier to add regex boolean features that
you wish to include in your final output to send to CRF++.  Simply make
a call to the function by passing in the characters(s) you wish to test
for with quotes around them.
