Nearest neighbour searchers now return number of points found for findPointsWithinR as well as marking them in input arrays. Also added new method sumDistanceAboveThresholdForPointsWithinRs() for the univariate searcher (to be used in spiking TE estimator under development)

Adding neighbour search utilities in preparation for attempting fast surrogate generation (performing multiple neighbour searches at once where we can); in particular adding a countPointsWithinR with a remapping of the point's indices. Unit test added as well for this.

Bug fix for Kraskov conditional MI algorithm 2 -- kdTrees for var1 and conditional, as well as var2 and conditional, were only being passed the radii for var1 (or var2) but not the radius of the conditional as well. This doesn't seem problematic at face value, however in traversing the tree the wrong radius was being used at levels corresponding to the conditional(s) in checking those nodes and determining whether their children needed to be traversed as well. Patched by implementing a new method in KdTree to take all radii in the situation where one variable has already been checked. Fixes issue 39.

Dynamic correlation exclusion, or Theiler window, added to all Kraskov estimators, i.e. Mutual Info, Conditional MI, Multi-info, and thereby the derived classes including transfer entropy. Fixes issue 35

Adding more methods to nearest neighbour search classes to return collections of points within ranges via arrays, and to use additional criteria in searching or take arguments for one variable that has already been tested. Utilising these new searches within Conditional MI Kraskov estimator algorithm 1

Adding fast nearest neighbour searcher for univariate data (uses only a sorted array rather than whole k-d tree). Adds an abstract nearest neighbour searcher so calling classes don't necessarily need to know whether they're dealing with uni or multi-variates. MI and conditional MI Kraskov altered to use this where possible.

Fixes issue 32 -- adds fast neighbour search to Kraskov conditional MI calculators (and by implication to TE calculators). Requires adding a neighbour search within different radii for each variable to the k-d tree class.
