Detailed Description

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

This class assumes field python field with spacedim arguments containing coordinates of the given point. The field should return a tuple representing a vector value (possibly of size one for scalar fields)

TODO:

use rather only one argument - tuple representing the whole point
time fields
set some parameter in the python module
for fields with one component allow python fields returning the value directly
