using mamory saving features (for low memory machines).
Sometime low memory stuff conflicts with other features,
like wf_collect and, for the time being, I prefer
to exclude them at compile time.

calculate the number of G-vectors and the dimension of G-vector arrays.
This should prevent mysterious errors in vc-relax. Harmless if the grid
dimensions are sufficiently large to accommodate all G-vectors; not sure
if they are not...beware unintended side effects

- Grid dimensions for both dense and smooth grids are in Modules/griddim.f90
- Variables describing G vectors and their mapping onto FFT grids (both
dense and smooth) are in Modules/recvec.f90
- FFT descriptors are defined in Modules/fft_types.f90
- Variables describing G-vector distribution across processors are
contained in Modules/stick_base.f90
- Distribution across processors of G vectors in sticks and planes
is performed in Modules/stick_set.f90, routine pstickset, which
also initializes FFT descriptors
- G vectors and their mapping onto FFT grids are calculated in
Modules/recvec_subs.f90 (routine ggen: a modified version of PW one,
replacing the CP one ggencp)
Testing is very limited but given the kind of modifications there should
be no major problem, I hope.
