Feature #2262: Add new isisminer application to system
GIS classes for providing an interface to GEOS-C system
This will add new functionality to the API. No impact on existing ISIS programs.
We can use the GEOS library to create singleton GisGeometry and GisTopology objects from WKB and WKT formatted gis specifications. We will also be able to write the geometry/topology to WKB or WKT.
A GisBlob class will also be added for storing footprint polygons.
