Restructured generation logic into separate templates
* root template iterates through the levels and calls the "process" template for each stylesheet
* the "process" template handles metadata extraction and main datasource resolution
** calls "compile" template for generation preparation
* the "compile" template resolves the support datasources, merges the final datasource and resolves the target path using additional helper templates
* actual generation of the result is preformed by the "generate" template as before
