Merge pull request #10 from JuliaStats/jmw

Use pdf() for ContinuousDistribution and DiscreteDistribution
Added PDF for MultivariateNormal
norm() -> det() for MultivariateNormal
Make Univariate / Multivariate distinction fundamental
Add tvpack and methods for two and three dimentional gaussian and t distributed variates. Professor Genz has agreed to my translation is used in Julia if a reference to his Fortran original is included in the source (and documentation when it is written). Added global rand methods for multivariate distributions.
