Bug fix to improve fit refinement with distortions
Added cubic spline routine.  Expt'l spectrum is splined to 2 kHz before peak-picking.
Users can now add additional transitions when refining fits.
Merge branch 'beaver'
pushed some old versions into /old and merged new changes from beaver and newcollege
New version - combines v13 and v13-isotopes into a single version.  Also has more flexible coordinate inputs.
Updated version of v14.  Includes bugfixes as well as brings back option for manual selection of fitting transitions.
Minor bugfix in scale factor code for isotopologue searches.
*Actually* fixed the bug this time...
v15 - final fit scoring now partially depends on experimental intensities (through both max/min ratios and std. dev.)
Merge branch 'beaver'
moved some old files over
Version tidying (moved several things to old) and added autofit_NS_module, intended to work with GUI in the future.
Merge branch 'newcollege'
Adding refit_module for eventual use with GUI.
Addition of isotopologue modules for eventual use with GUI.  See comments in files for differences between the two approachs.
Minor tweaks to slightly improve efficiency and get rid of a few useless lines of code.
