mmaelicke/scikit-gstat: Version 0.3

SciKit-Gstat is a scipy-styled analysis module for geostatistics. It includes two base classes Variogram and OrdinaryKriging. Additionally, various variogram classes inheriting from Variogram are available for solving directional or space-time related tasks. The module makes use of a rich selection of semi-variance estimators and variogram model functions while being extensible at the same time.

This version changed the DirectionalVariogram class quite substantially. The circular search area was removed, therefore shapely is not a dependency anymore and the variogram estimation for directional variograms got a performance gain of several magnitudes.
