Andreas Dedner requested to merge feature/femdg into master Mar 09, 2020

This MR contains the following changes:

fixed some issues with methods removed after the 2.7 release
improved the construction of grid functions. This change reduces the compile time of grids modules by 30%
added the option to construct grid functions by providing short C++ code snippets, e.g.,

code = """
#include <cmath>
template <class GridView> auto myFunction(double a) {
  return [a](const auto& en,const auto& x) -> auto {
    auto y = en.geometry().global(x);
    return std::sin(a*M_PI*(y[0]+y[1]));
  };
}"""
gf = gridView.function("myFunction",io.StringIO(code),2,)
gf.plot()

also added a method to import classes but this still needs additional features added
