Merge pull request #307 from rickhuizinga/polygon-static

Dramatically improved performance for large polygons
polygon

- example with "static" attribute added

server port changed from 3000 to 3100 to not interfere with rails
Added support for GeoJSON objects for path parameter/attribute in polygon & polyline directives.  This is in addition to the existing latitude/longitude object arrays.  Also added example page using GeoJSON coordinates, and example page with polygons containing a huge number of points to demonstrate the use of the new static parameter/attribute for the polygon and polyline directives
