Primarily this is used for testing if the code can handle user base. It is also, an example of how to build and use user approximation base. This is a test, so we used RT base by Demkowicz recipe.
Note that triple defines approximation element; element entity type, approximation space and approximation base. Entity type determines the integration method; approximation space determines the adjacency of the matrix and approximation base determines together with space the regularity of approximation.
