* approx.invert(): a new function to find the numerical
  inverse of a given side/alpha-cut generating function
  (by default via Hermite monotonic spline interpolation)

* convert.side(), convert.alpha():
  new functions to convert sides and alpha cuts
  to side generating funs and alpha cut generators

* FuzzyNumber class validity check for lower, upper, left, right:
   * checks whether each function is properly vectorized
      and gives numeric results
   * does not check for the number of formal arguments,
      but just uses the first from the list

* suggests `testthat`

* each object has been documented
