Piranha parameter parser:
* currently parses only parameter files, plan to extent to all ccl files
* is easier to expand and maintain than current hand-written parsers
* currently tested with ET test suite, needs to be tested on whole set 
of ET (and Cactus since it affects the flesh) machines
* should use namespace and adhere to Cactus naming and commenting 
conventions: either use C++ namespace cctk (and cctki?) and/or prefix 
all externally visible functions by either cctk or cctki depending on 
whether they should be user callable or not
* remove and replace existing math evaluator/parser by piranha one to 
have uniform math support
