  1. +Add Hybgen remapping options

      This commit adds the ability to specify three remapping options derived from
    Hycom's hybgen code.
    
     - Adds the new module MOM_hybgen_remap, which contains the new subroutines
       hybgen_plm_coefs, hybgen_ppm_coefs, and hybgen_weno_coefs
    
     - Adds code to handle PLM_HYBGEN, PPM_HYBGEN and WENO_HYBGEN as valid entries
       for specifying the ALE remapping schemes.  Also added descriptions of units
       to some internal remapping variables.
    
     - Adds the optional argument PCM_cell to regridding_main, remapping_core_h, and
       remap_all_state_vars to specify layers that should use piecewise constant
       remapping, regardless of the overall remapping scheme, to follow the approach
       used in Hycom.  ALE_main uses these new optional arguments, although until
       the Hybgen regridding code is added, they will always be set to false.
    
     - Makes 7 character strings longer in 5 files to accommodate the new
       remapping options.
    
    All answers are bitwise identical, but there are changes to some entries in the
    MOM_parameter_doc files.
