Merge branch 'master' of github.com:JuliaStats/Distributions.jl
Methods for working with distributions support added for univariate distributions. Please review carefully (repetetive work, easy to make mistakes).
Wasn't sure about EdgeworthAbstract distribution.
deleted incomplete method definition in fallbacks.jl
Used min/max also as infimum and supremum.
re-organized source files for conjugates
re-organized tests for conjuates-normal
Introduce IncompleteDistribution (in the place of GenerativeFormulation) and IncompleteFormulation to simplify generic codes
