New commit message* Replacing map_poly_shp_lonlat for map_poly_shp in base_choropleth_classif/unique/classless
* removed 'projection' from base_choropleth_classif/unique/classless
* Allow base_choropleth_classif/unique/classless to plot multi-part polygons properly
* changes streamlined to generic plot_choropleth
* Added dependency on pandas for rapid reindexing (this is done externally on the method _expand_values to it is easy to drop the dependency when neccesary/time available)
Minor fixes
Adding IP notebook to exemplify and keep track of development of mapping module
Replacing shp_link by shp as input for medium and low-level layers. This brings much more flexibility and opens the door to plot formats other than shapefiles (e.g. geojson)
*Replacing shp by map_obj in medium layer functionality. *Bringing everything else in line with it *Adding example for line colorig and mixing overlaying of points.
have Jenks-Caspal bins be a one dimensional array - to be consistent
with all other classifiers
Adding support for choropleth plotting on point map objects (this may come from map_point_shp or from a simple matplotlib scatter
Modifying example to show how to do choropleth mapping on points
Including support for points in  base_choropleth_unique and base_choropleth_classless
Adding caution note when plotting points to the notebook. Ideally, we wanna be able to build a PathCollection out of the XYs, but for now we rely on plt.scatter, which gets the job done but has some problems.
- update unit tests for reshaping jenks caspal
Merge pull request #356 from sjsrey/classification

Classification
Adding try/except for ogr since it's only used to reprojection methods but not on the plotting toolkit
more efficient connectivity test
