Variablies to be defined in FORTRAN namelist MERGEGRID:
&MERGEGRID
....

GRID1_IN : name of the file with 1st grid object           
GRID2_IN : name of the file with 2nd grid object 
           which will be merged into the first one

MTOL   : tolerance parameter for GRIDMAN_GRID2D_MERGE which 
         defines relative accuracy of the poits coordinates. 
         Default value is 1e-5. It might be necessary to increase
         or decrease TOL in some individual cases. If TOL is too large
         than the code can mistakenly take two different points 
         for one point. If TOL is too small then the code cannot 
         recognise what a point is sitting on the grid edge.  

GRID3_OUT: name of the file where the resulting combined grid
           is stored  

Grids are read and stored in GRIDMAN_GRID format

DBGMOD  : if .TRUE. then extra debugging output is produced.
          Default is .FALSE.
LCHECK  : if .TRUE. then standard check in GRIDMAN subroutines 
          are enforced.  Default is .FALSE.
