Changing the stepped potential interface to support the work done by Chris
A bugfix for the stepped potential class and a sketching out of the lennard jones class
Working on the lennard jones potentials
Initial implementation of the automatic stepped lennard jones potential
The stepped lennard jones potential appears to work now
Implemented most of the Lennard-Jones stepping
Added dynapotential to the tools package
Added virial stepping
Finished implementing dynapotential
Removed an unneeded header
Switched to the trapezium rule for the virial
Added the middle volume sampling approach
Make packed configs periodic by default
Fixed some erroneous behaviour in the script for the last step of the delta r and delta v systems
Merge branch 'experimental' of marcusbannerman.co.uk:dynamo into experimental
Added a fix for the left stepping potentials near r=0
Another numerical edge case added for the virial simulations
Trying to increase the numerical accuracy for virial integration as its sensitive for the constant volume stepping
Fixed a numerical instability in the virial stepping
Cleaned up the XML path construction to correctly detect the index of elements
