g_hydorder computes the tetrahedrality order parameters around a
given atom. Both angle an distance order parameters are calculated. See
P.-L. Chau and A.J. Hardwick, Mol. Phys., 93, (1998), 511-518.
for more details.
This application calculates the orderparameter in a 3d-mesh in the box, and
with 2 phases in the box gives the user the option to define a 2D interface in time
separating the faces by specifying parameters -sgang1 and -sgang2 (It is important
to select these judiciously)
