"""Ice Cube Solvator

Opens two md files, one with water in an ice structure,
and one with water in a liquid phase.   Deletes any overlapping
liquid molecules and merges the two md files.

Usage: waterRotator

Options:
  -h,  --help              show this help
  -u,  --solute=...        use specified meta-data (.md) file as the solute
  -v,  --solvent=...       use specified meta-data (.md) file as the solvent
  -r,  --rcut=...          specify the cutoff radius for deleting solvent
  -o,  --output-file=...   use specified output (.md) file


Example:
   iceCubeSolvator -u frosty.md -v tepid.md -r 4.0 -o lukewarm.md

3	gezelter	1116
4	kfletch2	1262	Opens two md files, one with water in an ice structure,
5			and one with water in a liquid phase. Deletes any overlapping
6			liquid molecules and merges the two md files.
7	gezelter	1116
8	kfletch2	1262	Usage: waterRotator
9	gezelter	1116
10	kfletch2	1262	Options:
11			-h, --help show this help
12			-u, --solute=... use specified meta-data (.md) file as the solute
13			-v, --solvent=... use specified meta-data (.md) file as the solvent
14			-r, --rcut=... specify the cutoff radius for deleting solvent
15			-o, --output-file=... use specified output (.md) file
