  - DerivLogf, Deriv2Logf and update.param print their progress
  - new function grow.grid
  - update.param handles interrupts by user and returns partially

                 Changes in version 0.3.3 (2016-06-23)                  

  - expr2f removed in favor of package Deriv
      - buildf returns a function in every use case
      - arguments changed for DerivLogf and Deriv2Logf
      - buildf, DerivLogf and Deriv2Logf use package Deriv to simplify
        and cache
  - nint_transform completely rewritten
      - takes a list of transformations
      - transforms interval and function dimensions
      - handles function dimensions correctly
      - implements transformation of function dimensions to interval
        dimensions
      - builtin transformations replaced by nint_tanTransform
  - refocus on D_A-optimality, arguments changed for Dsensitivity and
    Defficiency
  - argument names renamed for buildf, DerivLogf, Deriv2Logf, fisherI,
    Dsensitivity, Defficiency
  - FedorovWynn renamed to Wynn
  - defaults for method.args for numDeriv2Logf fixed
  - handling of nint_funcDim in nint_integrateNFunc fixed
  - performance increased for Dsensitivity and Defficiency
  - rowmatch uses C-code and requires matrices of doubles
  - plot.desigh recursively finds base design
  - plot.desigh won't draw second axis anymore if sensArgs$axes == F
  - typo fixed and default sensitivity label redefined for plot.desigh

                 Changes in version 0.3.2 (2015-10-14)                  

  - numDerivLogf and numDeriv2Logf optionally take a log likelihood
    function
  - sensitivity function redefined to a positive function, concerns
      - Dsensitivity
      - argument tol to FedorovWynn
      - new argument sensTol to plot.desigh

                 Changes in version 0.3.1 (2015-10-01)                  

  - buildf is more general

                 Changes in version 0.3.0 (2015-09-12)                  

  - class desigh redefined, constructor design added
  - major change in workflow
      - sensitivity function is 'liberated'
      - Dsensitivity builds a sensitivity function for D- and
        Ds-optimality
      - FedorovWynn takes a sensitivity function
      - related functions and their arguments are adjusted accordingly
  - component dDim removed from model definition
  - update.param also takes designs therefore replacing update.desigh
    and update_reference
  - new defaults for arguments dsNames and names

                        Changes in version 0.2.0                        

  - initial CRAN submission
  - start package versioning
  - all previous commits are considered irrelevant
