Detailed Description

Concrete implementation of the Det::measurements method for GeometricSearchDets.

It is done in a separate class to facilitate it's reuse from the various GeometricSearchDets.

The std::vector<DetWithState> passed to this method should not be empty.

In case of no compatible dets the result should be either an empty container if the det is itself incompatible, or a container with one invalid measurement on the det surface. The method does not have enough information to do this efficiently, so it should be done by the caller, or an exception will be thrown (DetLogicError).
