Not checking the right properties of beta diversity in tests, corrected error in calculation of ecosystem beta bar.
Added in Jost's alpha diversity measure and corrected documentation on our ecosystem alpha.
New documentation for Jost alpha and other fixes.
Merge branch 'master' of git://github.com/richardreeve/Diversity.jl
Error in calculating Jost's multiplicative beta diversity. Was calculated from our alpha not his.
Returning beta diversity measures to original values from arXiv paper, rather than deriving them from Dρ and Dϵ. We still need to resolve what difference these changes make, as both versions still pass all of our unit tests.
Master documentation commit
