Add Lagrange function with bubble on cubes

Simon Praetorius requested to merge feature/lagrange-with-bubble-cube into master

The MR adds a new local finite element that represents a multi-linear basis function on cube elements enriched by a single bubble function. The bubble function is a quadratic polynomial that vanishes on all facets of the element. This can be constructed as product quadratic edge functions (the product of the two vertex functions)
