2016-12-09 PySAL Legacy 1.13.0 Spatial interaction: new primer for spint
Geovisualization: geoplot notebook geotable-enabled plotting with matplotlib and bokeh backends, providing a high-level layer to integrate PySAL geometries in the plotting workflow. Choropleth mapping supported using palettable.

Moran plot function.
Bugfix of Distance Band Weights where named weights failed because indexing was not label-based
Multilple ways to construct spatial weights (GSOC).
Geotable module: extended the shapely extension to apply tabularly, and added some adapters between geopandas and pysal+pandas
Network docfixes.
GSOC spint: spatial interaction OD weights, vector-based Moran's I, sparse generalized linear modeling (GLM) module, nconstrained, production-constrained, attraction-constrained, and doubly-constrained gravity-type.
