* The Lennard-Jones repulsive term added to the F-P-F angle was too weak, allowing the structure to get trapped in a symmetric state with ~40º angles.

* The SHAPES-type simple fourier potential used for octahedral complexes has a fals minimim at 0º. Added a LJ 1/R^12 repulsive term between the two end atoms of the angle to prevent small angles. This required using tabulated potentials in LAMMPS.

* Fixed a typo in the angle type unit line which caused a crash
