Prepares data structures for calling fastDrawSample method next.
This method must be called once before using "fastDrawSample" (calling this more than once has no effect, but it takes time for nothing!) The behavior depends on the configuration of the PF (see CParticleFilter::TParticleFilterOptions):
The function pointed by "partEvaluator" should take into account the particle filter algorithm selected in "m_PFAlgorithm". If called without arguments (defaultEvaluator), the default behavior is to draw samples with a probability proportional to their current weights. The action and the observation are declared as "void*" for a greater flexibility. For a more detailed information see the Particle Filter tutorial. Custom supplied "partEvaluator" functions must take into account the previous particle weight, i.e. multiplying the current observation likelihood by the weights.

The corresponding node in the HMT map is updated with the robot poses & SFs in the LMH: the poses are referenced to the area's reference poseID, such as that reference is at the origin.
If eraseSFsFromLMH=true, the sensoryframes are moved rather than copied to the area, and removed from the LMH.
