Fixed variance of MixtureModel
Passed on normalized probabilities to AliasTable
added support in variance for multivariate distributions
remove dependency on NumericExtensions
remove dependency on NumericFuns
use svg travis logo
Updated rand! for mvtdist (was broken after NumericExtensions was removed from REQUIRE)
Removed bdivide! from rand! in mtvdist too
Used broadcast! to replace bdivide! and badd! in rand! of mvtdist
Binomial TPE sampler, KS test for discrete vars
Add Poisson samplers
Sampler type, Gamma samplers
Merge pull request #245 from JuliaStats/binom-rand

Sampler abstract type, implement julia Binomial and Poisson samplers.
rearrange Exponential methods
typo
sampler types moved to StatsBase
categorical samplers migrated out to StatsBase
require StatsBase 0.5 (using Sampling interface there)
depend on sampling
improve Laplace rand, rearrange methods
