change fit_mle to fit for Cauchy (the current implementation is not MLE)
Enhanced estimation interface for Categorical
More functions for estimating Categorical
Enhanced interface for Binomial estimation
add @inbounds for Gamma estimation
minor rearrangement of Dirichlet estimation code
@inbounds for Dirichlet estimation
add Estimator type and interface

This is a nonintrusive modification. By delegating estimate(e::MLEstimator, x) to fit_mle, we no longer need to make any change to original codes.
include estimators.jl
Implement posterior_mode and fit_map for a series of distributions.
Change parameterization of InverseGamma (using the wikipedia way)
Fix Normal characteristic and moment generating functions
