Merge fixes and feature comparison fixes
Merge pull request #74 from JimHokanson/master

Fixed eccentricity and setup initial code for change to config approach
Added MIT license information
Update README.md
Fixed circular dependency

morphology_features imports WormFeatures, but WormFeatures
imports
morphology_features.

I fixed this by moving
WormFeatures._extract_time_from_disk to utils.py
so that
morphology_features no longer needs to import WormFeatures.

Deleting user_config.py

This file should not be in the repo itself.  Users should sync to the repo and then copy user_config_example.txt to user_config.py to make their own personalized version.

.gitignore will then be able to ignore it.
Major refactoring

Major in the sense that the parent directory has changed, from src to
movement_validation.

Also __init__.py is simplified.  It's not BLANK at the root level
though, because otherwise you'd have to do this and this seems annoying:
from movement_validation.features.WormFeatures import WormFeatures

better to say (in my opinion):
import movement_validation

then you can refer to movement_validation.WormFeatures
Delete user_config.py

I don't really understand why I keep having to delete this, it's in the .gitignore file!
Update .gitignore

Fixed /src/user_config.py to /movement_validation/user_config.py
Editing documentation

Fixed copyright notice to include the mandatory MRC notice.

Consolidated all contributor information, which was previously randomly
in each source file, into a "THANKS.md" file

Added a LICENSE.md, simplifying README.md
Small changes to license

Also removed some unneeded code in __init__.py
Major documentation overhaul

Simplified the main README.md, moving much of its content to other
places.

I took as inspiration the documentation structure for the [numpy
repository](https://github.com/numpy/numpy)

I also added a "Guide for contributors" that includes a history of the
repository to clarify things for them.
Minor edits to documentation
Added Peter McCluskey's gist

It recursively traverses a feature file and plots every time-series.  It
might be useful to use in the future.
