Fixed norming bug in SEPP - this has been annoying for AGES.  Hopefully no need for further changes.
Added hotspot comparison method that uses a var bandwidth KDE to build a hotspot in a similar way to the SEPP method.
Initial results suggest that this has about the same level of effectiveness as the SEPP.  More testing required (TODO).
Amended Chicago validation code.
Started modifying plotting code towards the goal of making a movie of the SEPP output.  TODO: need to be able to specify levels?  TODO: some weird issue with intensities getting larger as time moves on?
Created new RocSpatial class to deal with the specifics of gridding a region and computing various performance metrics on it.
Removed references to old code in validation classes and replaced with new code.
TODO: add tests for new RocSpatial class.
Amended create_spatial_grid function so that it now outputs extent coords as well as polygons - much faster for computing true counts in grids.
Switched pickle to dill to allow pickling of lambda functions when running validation.
Fixed minor merge conflict in SEPP models.  Small change to chicago code ?
