Subject: Implemented StylesheetParameterGuard class * removes responsibility
 for clearing parameters from the generate member methods * abstracts
 parameter escaping and setting and handles map conversion * marked actual
 generate member method as private and added StylesheetParameterGuard
 reference argument ** "frontend" generate member methods instantiate a
 StylesheetParameterGuard instance and pass it to the actual generate method
 ** this enables central default parameter definition while offering the
 possibility for custom parameters
