2023.9.7

2023.9.6

* 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.

2023.8.27

* 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.

2023.5.1

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

2023.4.6

* An initial set of parameters for cathode materials, specifically LiCoO2.

2023.2.13

* Added parameters for OPLS-AA along with some extra parameters for ionic liquids
* PF6-
* ethylene carbonate (EC) and fluoronated EC (FEC)
* Added atom-typing templates for most of OPLS-AA. Still missing a few and amino
acids and DNA not yet tested.
* Added extensive, almost-complete testing, for OPLS-AA
