dft_lin_respao performs the transformation of given transition density

Parameters:

	vec	and the result is stored in
	trans_vec	- both of which are square matrix A ground state density
	dens	is required.
	bis	is the basis set description structure.
	mol	contains the molecule data (is this strictly needed?)
	gss	a structure describing the grid settings.
	nThreads	tells how many threads execute this section (needed for grid).
