/** \brief Mathematical expressions parser (base parser engine).
\author (C) 2013 Ingo Berg
This is the implementation of a bytecode based mathematical expressions parser.
The formula will be parsed from string and converted into a bytecode.
Future calculations will be done with the bytecode instead the formula string
resulting in a significant performance increase.
Complementary to a set of internally implemented functions the parser is able to handle
user defined functions and variables.
