first pass: adding mapbox vector tile support. (geometry encoding is a WIP for now)
cleaning up - naming and removing commented lines out
Manual zig zag encoding + geometry encoding (first pass)
re-writing the encoding with while loops. handle unicode encoding str values.
making coordinates an array of objects that have vertex2d info (x,y,cmd)
One step closer - flipping y upside down correctly, starting the tile with 0,0 moving coords out of addFeature(), not multiplying x,y coords with path_multiplier becuase the query takes care of it.
removing GeomEncoder - using shapely.wkb's loads instead for parsing purposes. cleaning up mapbox - splitting into more meaninglful functional blocks
ignoring key,value pairs where value is of NoneType. (ex: when natural, landuse, kind is None, nothing will be sent)
encoding exterior and interior polygons correctly by treating each ring/arc seperated with their MOVE_TO and SEG_ENDs. This simplifies things because the cmd logic is now part of the parser/builder that builds the cordinate array - we no longer need _process_points and _get_cmd_type functions
