- consolelogger.h to only detect whether begin member function exists
- refactor of coordinates from pointer to std::array

whether the varible is iterable and then writes the content of the
container.

MeshDataContainer implicit constructor added

inline_array_operations.h -> reorder of operations

Mesh Colouring
MeshDataContainer

Setup of boundary cells
Cells distace over face

integer_sequence
Refactor of methods

class UnstructuredMesh has no specializations now

different types to mesh elements is also done.

correct.

I realized, that it would be better to implement methods working with mesh elements in the class UnstructuredMesh.
Finally, I managed to implement concept of unstructured mesh in any dimension.
Further work will be done after consultations.

Now the intent is clear and only few things like center points are to be implemented.
Then create wrappers for cells, faces etc.
Also is necessary to create methods for calculating lebesgue meassure.
