I recompiled mgridder.f to increase the number of allowed input points from 300000 to 1000000 and the max # of grid points to be 50000.

I used the g77 compiler in cygwin window on my fujitsu laptop (lager) to do this.

g77 -o mgridder mgridder.f

I modified this file to read the input arguments from the file gridparfile.txt, which is created by the m-file creategrid.m.
The input arguments are: input data filename, output gridded file name, number of columns, and number of rows in grid.

This avoids having to pass the arguments to mgridder.exe using the cygwin shell script mgridders.  The latter seemed to stop working for some unknown reason.

I also modified creategrid.m and realbugplot.m so that they write gridparfile.txt and run mgridder.exe
