Compute alpha diversity metrics

Note that the Simpson index here is the probability that two individuals randomly drawn will be of the same taxon, and thus gets larger as diveristy *decreases*.

richness(x)

simpson(x, proportion = TRUE)

shannon(x)

`x`	A matrix with rows as sites and species as columns. Values are abundances or presence/absence
`proportion`	Logical. If true, abundances in x are considered proportional abundances. If false, x will be transformed to proportional abundance

A vector of diversity values
