More geofence types need to be supported #216

Hi,@tidwall I found that ArcGIS's geoevent is much like tile38's geofence, and it provides 12 spatial filters:

INSIDE, OUTSIDE, ENTER, EXIT,CONTAINS, CROSSES, DISJOINT, EQUALS, INTERSECTS,OVERLAPS, TOUCHES, WITHIN

It seems that it not only supports the judgment of points, but also supports the judgment of lines and polygons.

Tile38 provides 6 spatial filters, it would be great if it supports the rest of 6 spatial filters :)

Hi @icewukong,

Some of these events may make sense, though I would need to study up on the ArcGIS geoevent service. Is there a link online to a technical document describing these event?
