[geotk] Geometry operations in Geotk

[johann sorel]

Hi Jon,

We use JTS for geometries for now.

 > Here is an example to create geometries :
https://github.com/Geomatys/geotoolkit/blob/master/demos/geotk-demo-samples/src/main/java/org/geotoolkit/pending/demo/geometry/JTSDemo.java

 > All operations are on the JTS geometry class.
boolean intersect = geom1.intersects(geom2)

 > For reading and writing you have WKTReader and WKTWriter, same for WKB.
WKTReader reader = new WKTReader();
Geometry geom = reader.read("POLYGON(....");

 > For transformation between CRS.
Geometry geom2 = JTS.transform(geom, crs1ToCrs2);
