Detailed Description

template<int spacedim, class Value>
class FieldFormula< spacedim, Value >

Class representing fields given by runtime parsed formulas.

Using library: http://warp.povusers.org/FunctionParser/

TODO: correct support for discrete functions (use integer parser), actually we just convert double to int
