Message:

Two new bond analysis functions.

• GetMaxMinMeanBondCount() - evaluates min, mean and max bond count
• MinMaxBondDistanceBetweenElements() - evaluates min, mean and max bond distance
• Unit tests are in place and working fine.

Location:

src/unittests

Files:

• analysisbondsunittest.cpp (modified) (7 diffs)
• analysisbondsunittest.hpp (modified) (3 diffs)
