GeoDa 1.14.0

There have been many commits since 1.12.x. The primary focus of this release is on bug fixes and incremental improvements, however there is a usual lot of new features as well, including:

Cluster:

Add fast HDBSCAN method
Add Redcap methods
Add Local Join Count method
Add auto-weighting function
(GeoDa now has a suite of Spatially Constrained Cluster techniques, including skater, redcap, max-p, k-means, k-medians, k-medoids, and spectral clustering. )

Mapping:

Add multi-layer support (+ map boundary, point size, stroke/fill color, etc.)
Support HDPI on Mac OSX in all maps and plots
Add Map layout preview tools for saving map w/ legends and plots in high resolution
Add configurable Basemap options
Add re-projection function when exporting a map
Add Spatial join and spatial aggregation
Add colocation map

Weights:

Add social-weights creation
Add support for ArcGIS .swm format, Matlab .mat format
Add weights intersection and weights union
Add weights network graph, (minimum) spanning tree as weights and network graph

Internationalization:

Add internationalization framework
Chinese version and Spanish version

For Linux, GeoDa now supports Ubuntu 16.04 and 18.04 with GTK 3.0, which is more stable and has better rendering quality and performance.
