A constraint between two landmarks in separate maps Templated on: Point : Type of landmark Transform : Transform variable class.
The transform is defined as transforming global to local: l = lTg * g
The Point and Transform concepts must be Lie types, and the transform relationship "Point = transformFrom(Transform, Point)" must exist.
To implement this function in new domains, specialize a new version of Point transform_point<Transform,Point>(transform, global, Dtrans, Dglobal) to use the correct point and transform types.
This base class should be specialized to implement the cost function for specific classes of landmarks
