Add function to generate grid of possible poses for Rig

Done in a similar fashion as random poses generation,
taking into account the possible space limits for poses.

Changes to CRawlogLRF to add Blender support and metafile preassigment
Refactor R0 and t0 propeties to R and t

By default all methods should use these properties as input R and t if needed
and store the new results in them too.
Add R uncertainty in the computation of weights for t optimization
