Calculates similarity-sensitive raw metacommunity alpha diversity (the
naive-community metacommunity diversity). This measure may be calculated
for a series of orders, represented as a vector of qs.
raw_meta_alpha(meta, qs)object of class metacommunity
vector of mode numeric containing q values
raw_meta_alpha returns a standard output of class rdiv
