Changes to OP
- Added a 'setup' method that must be called prior to calling 'run'
- This means that algorithms can be 're-run' just by calling 'run()' with no arguments.
- If you want to change the way it's run you just call 'setup(with all the arguments you want')
Adding throat_vector submodule to Geometry
- included one method for find the vector based on a direct path between pore centers
- outputs a normalized vector of unit length
