synthpop 1.1-0
---------------

NEW FEATURES
* Function sdc() for statistical disclosure control of the synthesised data 
  set(s); function replicated.uniques() to determine which unique units in the 
  synthesised data set(s) replicates unique units in the original data set.    
* Function read.obs() to import original data sets form external files.
* Function write.syn() to export synthetic data sets to external files and 
  create a text file with information about the synthesis.
* syn() has new `semicont` parameter that allows to define spike(s) 
  for semi-continuous variables in order to synthesise them seperately.
* `lognorm`, `sqrtnorm` and `cubertnorm` methods for synthesis by linear 
  regression after natural logarithm, square root or cube root transformation 
  of a dependent variable.  
* `seed` argument for syn() function.

CHANGES
* Revised output of summary.fit.synds() and compare.fit.synds(); 
  standard errors of Z scores corrected (se(Z.syn)) 
  (thanks to Joerg Drechsler).
* Figures for compare.fit.synds() and compare.synds() functions plotted 
  using ggplot2 functions.  
* period.separated or alllowercase naming convention has been adopted and 
  parameter names `populationInference`, `visitSequence`, `predictorMatrix`,
  `contNA`, `defaultMethod`, `printFlag` and `nlevelmax` have been changed to
  `population.inference`, `visit.sequence`, `predictor.matrix`, `cont.na`,
  `default.method`, `print.flag` and `minnumlevels` respectively.
* Default for drop.pred.only changed to FALSE.

BUG FIXES
* Rounding procedure (thanks to bug report by Joerg Drechsler).
* Warning about extra disregarded argument `family` in compare.fit.synds().
