Projectors are non-trivial in non-orthogonal spaces, cf

Soriano, M., & Palacios, J. J. (2014). Theory of projections with nonorthogonal basis sets: partitioning techniques and effective hamiltonians. Physical Review B, 90(7),
1. http://dx.doi.org/10.1103/physrevb.90.075128

It could be useful to implement them in CompactBases.jl.
