rbOOmit change: There was a bug for complex-values in RBConstruction::enrich_RB_space which
meant that basis functions were not orthogonal. Here we commit the simple bug fix and also
add some debugging info to reduced_basis_ex1 and reduced_basis_ex7 that prints out
the inner products between basis functions to make sure that they are accurately
orthogonalized.
rbOOmit change: Another small fix regarding complex-values. This one should
not affect anything since the RB_inner_product_matrix is not used in
complex mode at the moment.
