= Explanation of organization of data: A point is psi(kx,ky,kz)

Each gStateSlab is a collection of pts in lines of constant kx,ky. The maximum number of pts in any line is size[1] = nfftz Some lines are longer/shorter to spherical trunction (|k|<k_cut). Also, kx>=0 when at the Gamma point or doublePack=1, the only thing that has been recently tested. Collections of lines are parallelized. Each collection does not correspond to a unique plane of kx. The parameter gSpaceUnits is obsolete and must be unity. In order to create the state in real space, psi(x,y,z), an fft of all kz lines is performed followed by a transpose. The result of the transpose is parallelized by planes of z. This is different than it used to be. The number of points AFTER the fft is nlines*nfftz will be different for each chare array

= Explanation of the organization: Each CP_State_RealSpacePlane instance is actually a planes of psi_I(x,y,z). We index into planeArr using the z-coordinate and each chare is an x-y plane. Data arrives from the gspaceplane of total size : nlines_tot*nfftz
