Calculates shape and scale parameters for a gamma distribution from the mean
and standard deviation of the distribution, or vice-versa. One supplies
either `mean`

and `sd`

or `shape`

and `scale`

and the
function returns a list with all four parameter values.

A list with `mean`

, `sd`

, `shape`

and `scale`

parameters of the corresponding gamma distribution.
