XtalOpt r12.3

This is an attempt to stop a bug that is occurring very rarely, but when
it does occur, it prints to a log file non-stop until the disk runs out
of memory. This is very bad on shared disk space.

What will happen now, in theory, is, that when a crystal fails to generate
10000 times in a row:

1. The error message will have printed 10000 times to the log file.
2. The program will print a message which indicates to us where exactly
   in the code the issue is occurring.
3. The program will crash.

That's my guess as to what will happen. We will see what actually happens
next.

It seems this bug occurs mostly in CLI mode.

XtalOpt r12.2

For CLI mode, use zero-based indexing

It appears that zero-based indexing should be used here. It was
perhaps one-based indexing before. Hopefully, this will fix the
issues we have been facing.

XtalOpt r10.0

Release 10.0

• Implementation of RandSpg, an algorithm that generates random crystals with specific spacegroups. This algorithm can optionally be used to create symmetric structures in the initial random generation.

• Inclusion of variable forumla units within XtalOpt enables the search for cells with multiple numbers of formula units within a single run.

• A molecular-unit generator permits users to create single-center molecules in the unit cell during the initial generation step.
