ParamHelpers_1.2:
- normal parameters can now have a default value
- parameter spaces can now define a forbidden region of infeasibility.
  all operations on the set respect this, although a few are disallowed and produce an exception.
- rewrote generateDesign and dfRowsToList in C to greatly increase speed in
  the case of dependent parameters
- generateDesign and generateGridDesign do not support type conversion anymore. See help page.
- generateDesign now ensures that no duplicted settings are produced in rarer cases
- Added option to log error messages, execution time and extra info in the optimization path.
- slightly change interface of getOptPathY, so one can now return a matrix of multiple measures.
- paramValueToString produces better readable output
- sampleValue(s) have new option "trafo"
- getLower and getUpper have with.nr argument now
- getTypes renamed to getParamTypes
- new functions
-- isNumeric, isDiscrete, isInteger, isLogical
-- hasNumeric, hasInteger, hasDiscrete, hasLogical
-- getParamNr
-- getDefaults
-- hasTrafo, hasRequires
-- isForbidden, hasForbidden
-- generateGridDesign
-- getOptPathExecTimes, getOptPathErrorMessages
-- getOptPathParetoFront

ParamHelpers_1.1-35:
- concept of dependent parameters was introduced (argument "requires")
- as.data.frame.OptPath: discretes.as.factor option
- all arguments "length" renamed to len
- new functions
-- convertParamSetToIrace
-- dfRowToList, dfRowsToList
-- getOptPathDOB, getOptPathEOL
-- hasRequires
-- removeMissingValues

ParamHelpers_1.0-55:
- disabled one unreasonable unit test for CRAN
- some dependencies are now imports like they should be

ParamHelpers_1.0-54:
- First submit to CRAN.
