added wakeby as rv_cont distribution
use numpy's sum for arrays
error corrected
code re-organising
use of scipy built-in distributions, code improvements
added GNO as `rv_cont` distr. Removed lmoment3's own implementations of distributions supported by scipy.stats.
moved AIC and BIC calcs to seperate `stats` module. `pelxxx` functions now return distribution parameters as a dict.
pelxxx returns ordereddicts
use `scipy` native negative log likelihood
