Kierran Falloon 775a73b67c cgDNA 'real' units and potential file reading for non-modifiable potential parameters (#15)
* oxDNA potential file reading and real units

This allows for pair and bond coefficients to be read from an appropriately formatted potential file, and also allows for the use of 'real' units within oxDNA1. The correct backend coefficients for pair and bonded interactions are set when the atom vector is initialised through the "ConstantsOxdna" class, based on the units specified within the input file.

* Extract seqav/seqdep and temp from potential files

Also includes miscellaneous string consistency changes and removes unnecessary parameter from reader.next_line instances.

* oxDNA2 potential file reading and real units

This extends previous changes to oxDNA2 specific potentials, being FENE, excluded volume, coaxial stacking and Debye-Hückel. Units now default to LJ values rather than 0.

* oxDNA potential files

* LJ <-> real units conversion tool

Converts standard oxDNA data and input file to real units, with inverse flag available for real -> LJ.

* oxRNA2 potential file reading and real units

For RNA, d_cs_x is treated as d_cs within ConstantsOxdna in order to reduce code duplication and complexity.

* Reparameterise real units

* Generalise PotentialFileReader logs

* Extract stk xi and kappa from potential files

This allows users to edit these values from the input script, as is documented, rather than them being within the potential files.

* Real unit and potential file documentation

This adds examples for real unit parameters and specific potential file documentation for each bond and pair style.
