slight cleanup. D --> E format.
enforce small tolerance (cutbase) to make epsPP_lmfh safer.

We needed to use small enouth tolerance for product basis (tolopt) for
epsPP_lmfh because of ptest mode (echo 4|hbasfp0). It is enforced to be 1d-6 now.
epsPP_lmfh_chipm automatically set QGpsi=QGcou=0 (no change with previous results).

Thus ngp=ngc=0 as shown in the output lqg4gw02.
new mode echo 4|qg4gw. (set QGpsi=QGcou=0).
