Detailed Description

template<class FunctionSpace, class Function>
class Dune::Fem::BasicInstationaryFunction< FunctionSpace, Function >

basic wrapper class (still a CRTP) for instationary functions

This class implements two methods

double setTime(double);
double time() const;

for wrapping some time dependent function and making it a Dune::Fem::Function that may only depend on spatial variables.
