Calculates similarity-sensitive normalised metacommunity rho diversity (the
average representativeness of subcommunities. This measure may be
calculated for a series of orders, represented as a vector of qs.
norm_meta_rho(meta, qs)object of class metacommunity
vector of mode numeric containing q values
norm_meta_rho returns a standard output of class rdiv
