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.
