Check if shapes match when adding interpolations/cells

[Psirus]

Previously, when you called AddDofInterpolation with a quad interpolation on a mesh full of triangles, it finished without complaining, adding nodes at weird locations. This checks if the shapes of the two interpolations are the same.

The same applies for adding cells with an ElementCollection and an IntegrationType.

Also fixed a couple of typos and added outstream operators for the shapes.

Hehe, it already found a bug^^

In the StructuralGradientDamage test (specifically, here), we are trying to integrate line elements with a triangle integration type:

IntegrationTypeTriangle integration(4);
auto cellsLeft = cellStorage.AddCells(leftElements, integration);
