[RegCNET] shifted grid on the projection plane

[Peter Huszar]

Dear RegCM users,

I really miss some feature in RegCM. When defining the domain grid, users
are restricted to center the domain to the projection center  without any
possibility to define an arbitrary shift on the projection plane. The root
of the problem is, it seem, in the
PreProc/Terrain/mod_maputils.F90
at lines (in version 3.6.1)
    cntrj = real(jx+idot,rkx)/d_two
    cntri = real(iy+idot,rkx)/d_two
where this asummption is implemented and setup_lcc is called with this
central (i,j) afterwards.

Could this be changed to any cntrj, cntri (of float value) in order to
shift the grid? This would faciliate e.g. to match RegCM grids with WRF
(for comparison studies) grids which are not centered in the projection
center, in general.

Anyone did some (working) modifications in this regard?

Thanks a lot in advance
Peter
