Extended the canMerge test. Bit crap but just testing.
Using bit flags set by the children to say if they're safe to merge or not. Not quite right yet.
Pi.cpp - try and wait until all jobs complete before shutting down.
GeoSphere, remove all of the threading stuff.
So many other little changes.
Split the GeoSphere stuff into GeoPatch and GeoPatchContext files.
Lots of tweaks and changes but still massive problems with Release mode :(
