CRAN v0.3.1

New features

• Add Math and Ops methods for sample distribution, which applies the functions
  directly to the samples.
• Added mean and sd as aliases for mu and sigma respectively in
  dist_normal() and dist_student_t() to match arguments of the stats package
  interface (#76).
• Added scale argument for alternative specification for dist_burr() and
  dist_gamma().

Improvements

• Generics introduced by this package now allow na.rm and other parameters to
  be passed to distribution methods, even if these parameters aren't used. The
  package no longer checks the usage of ... with the ellipsis package, if
  you'd like to check that all ... are used, you can write your own wrapping
  functions.
• Lists of functions can now be used in dist_transformed(), allowing the
  transformation to differ for each distribution.
• covariance() and other matrix output functions of multivariate distributions
  now name the result using the distribution's dimension names.
• Improve handling of mixture distribution quantiles at boundaries {0,1}.

Bug fixes

• Fixed issue with computing multiple values from a univariate distribution with
  named dimensions (#79).
