1.9.1

• New function, bestLogConstant, that uses the same machinery to pick the best
  value of a constant to use when logging a variable, e.g. the one that makes
  the distribution look the most normal, especially useful for non-positive or
  zero-inflated data. Currently experimental.
• Taking out tests that failed due to dependent package update (does not impact default bestNormalize behavior). See (issue)[https://github.com/gmgeorg/LambertW/issues/3].
