Assembles the cross mass matrix between to function spaces.

Parameters

[in]	is_volume	True if the mesh is volumetric.
[in]	size	Size of the problem (e.g., 1 for Laplace).
[in]	n_from_basis	Number of basis functions in the initial function space.
[in]	from_bases	Finite element bases to map from.
[in]	from_gbases	Geometric bases to map from.
[in]	n_from_basis	Number of basis functions in the resulting function space.
[in]	from_bases	Finite element bases to map to.
[in]	from_gbases	Geometric bases to map to.
[in]	cache	Assembly values cache.
[out]	mass	Output constructed mass matrix.
