Public Member Functions
	CBinnedMassRefinementFnc (const COrbitLibrary *orbitlib, size_t numBins, const CBasicOrbitFilteringFnc *_evalFnc)
	initialize bin boundaries by sorting the output of evalFnc for all orbits in the library
virtual double	eval (const COrbitDesc *orbit) const
	return the bin into which the orbit falls, using the pre-initialized array of bins

Private Attributes
const CBasicOrbitFilteringFnc *	rankFnc
	the evaluation function; orbits are sorted according to the value returned by this function
vectord	binBoundary
	divide the entire orbit library into numBins; the bin boundaries in terms of evaluation function values are stored in this array

Detailed Description

A mass refinement function is used to create an Nbody snapshot with unequal mass particles.

It ranks orbits into several bins, based on another evaluation function passed as a parameter; mass factors of adjacent bins differ by a factor of two, and each bin contains the number of orbits that also differ by a factor of two. Used in creating multimass Nbody models: one may wish to have a better mass resolution for the inner parts of the model, based on orbit energy, or pericenter distance, or anything else.
