1) Fixing bug https://github.com/searchivarius/NonMetricSpaceLib/issues/4
2) Splitting JS into JS-div and JS-metric
Merge branch 'master' of github.com:searchivarius/NonMetricSpaceLib
1) Making two spaces of a formerly cosine
2) Adding dense cosine/angular distances.
Both dense and sparse seems to be buggy though.
Mostly fixing alignment issue
