make_relative

From an abundance matrix (numbers of individuals of a given species at a
site) returns a relative abundance matrix (proportion of individuals of a
given species at a given site). This function works also
with sparse matrices.

Computes functional rarity indices as proposed by Violle et al.
(2017) <doi:10.1016/j.tree.2017.02.002>. Various indices can be computed
using both regional and local information. Functional Rarity combines both
the functional aspect of rarity as well as the extent aspect of rarity.
'funrar' is presented in Grenié et al. (2017) <doi:10.1111/ddi.12629>.
