Calculate Tirion's model from pdb structures

Official package sites : ·

A fortran program in which Tirion's model (also called the Elastic Network Model) is implemented. Within the frame of this model, atoms (particles) less than cutoff (angstroms) away from each others are linked by springs of same strength. Alternatively, a list of interacting atoms can be given to the program. Requirements: a file with the coordinates of the system, in PDB (Protein Data Bank) or "x y z mass" format. Output: the hessian (the mass-weighted second derivatives of energy matrix), in the "i j non-zero-ij-matrix-element" format. Diagstd, a fortran program with a standard diagonalization routine, can next be used in order to obtain the corresponding normal modes of the system. If the system is large, the RTB approximation can prove usefull (see below).

proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
