0.13.0 : GeoSeries & MultipleGeoSeries; revamped maps

This version introduces 2 new classes, GeoSeries & MultipleGeoSeries, which parallel Series and MultipleSeries, respectively.
GeoSeries is the more general substitute for LiPDSeries, which will be deprecated soon.
Both classes enable new mapping capabilities, supported by seaborn to allow semantics that leverage shape, color and size to represent multivariate information in space. MultipleGeoSeries allows geolocated principal component analysis.
This release also includes minor bug fixes, particularly on the handling of time metadata.
