Subject: Replaced FunctionTransform by making the target of FunctionGenerate
 optional * if the target parameter is not provided FunctionGenerate now
 performs exactly the same functionality as FunctionTransform * added
 "boost::optional<boost::filesystem::path>" specialization to the XObjectValue
 class * modified test cases accordingly * modified README.md accordingly
