[gmx-users] combine two gro into one

[Sikandar Mashayak]

yeah I know its simple, but only concern I have is that, the index of
atom/residue in two files may not be in agreement, so I have to change/shift
index of atoms in one of the file.

but anyway I guess I will have to do it manually....

thanks
