Lateral diffusion: latdiff.f

This utility computes two-dimensional mean square displacement in membrane-like systems and the lateral diffusion coefficients. It works essentially as diffus utility with a few exceptions:

- parameter

IRT = <int.value>

defines type of ``lipid'' molecules (that is molecules which build the membrane)

- if parameter

LCOM = .true.

is defined, then MSD of lipids are computed relative to the center-of mass motion of each monolayer.

- in definition of lateral diffusion, factor 1/4 is used instead of 1/6 in 3D-diffusion.
