`gleverage`

is a new generic for computing generalized leverage values as suggested by
Wei, Hu, and Fung (1998). Currently, there is only a method for `betareg`

models, implementing
the formulas from Rocha and Simas (2011) which are consistent with the formulas from
Ferrari and Cribari-Neto (2004) for the fixed dispersion case.

Currently, the vector of generalized leverages requires computations and
storage of order *n x n*.
