new Browndye release

[Gary Huber]

Dear Browndye Users,

We have a new release.  Among other things, this release includes the ability to set a constant time step for individual chains.  This could be handy in cases of a COFFDROP chain interacting with a rigid core that "freezes" when it is not near its binding site.  

Also, I corrected the documentation regarding the chain file. Each "bond" tag must be inside the "bonds" tag, and likewise for other structures.

Happy New Year!

Gary
