This package contains a user-created expansion to LIGGGHTS-PUBLIC.
Specifically, this ... to LIGGGHTS, like ...
... and others. You will find examples on
how to use this package in examples/BondPackage. This is an updated
version of the bond package first completed by richti83 for LIGGGHTS
3.3 (https://github.com/richti83/LIGGGHTS-WITH-BONDS) and further 
enahnced by schrummy14 for LIGGGHTS 3.8 
(https://schrummy14/LIGGGHTS_Flexible_Fibers). If you find
this work helpful to you, please also reference the following papers,
along with the LIGGGHTS paper.
