Smurfs

- Errors are now put through to results
- Results file are created as csv
- Nyquist frequency is added to results
- Final fix to phase corrections :)

Features
* SMURFS catches Control+c in terminal and dies graciously
* SMURFS creates dynamic fourier plots, including the possibility for markers (_-fm_ parameter)

Bugfixes
* Gap Ratio is only calculated when the whole dataset is used, i.e. _-trs_ is not set
* Nyquist frequency calculation is now fixed. Used to use the mean of the difference between two datapoints, now applies a histogram and uses the most common value.

With this release, the code should handle fitting as well as problematic data better

Initial release for SMURFS.

Should be generally feature complete, but we will wait for a short beta period until we will it release properly
