Detailed Description
template<int spacedim>
class ElementAccessor< spacedim >
Element accessor templated just by dimension of the embedding space, used by Fields. This should allow algorithms over elements where dimension of particular element is runtime parameter.
This class suites as interface of Fields to the mesh elements, in particular this accessor knows directly the region, and also can be used as an accessor that works on the whole region if used by Fields that do not depend on particular elements as FieldConstant, FiledFormula, and FieldPython.
TODO:
- make this kind of accessor subclass of FieldCommonBase or at least move it into src/fields since it has functionality particular for Fields
Ideas: need function to calculate intersection (object) of two ElementAccessors, but this definitely should be templated by dimension of the ref. element (or rather shape of ref. element), here we can have case dispatch
