Development files for libfparser

This C++ library offers a class which can be used to parse and evaluate a mathematical function from a string (which might be e.g. requested from the user). The syntax of the function string is similar to mathematical expressions written in C/C++ (the exact syntax is specified later in this document). The function can then be evaluated with different values of variables. For example, a function like "sin(sqrt(x*x+y*y))" can be parsed from a string (either std::string or a C-style string) and then evaluated with different values of x and y. This library can be useful for evaluating user-inputted functions, or in some cases interpreting mathematical expressions in a scripting language.
