improved exception handling in FileLoader.getFeaturesFromEquationFile
FSTGenComposer: extracted loadFiles, removed conf member
added --no-compose to support FSTGenComposerExtension:
- moved code generation from AbstractCompositionRuleset back into composer
- adapted Rulesets: ruleset hooks are called even if no composition happens
- commented FSTGenComposer.run
removed unused imports and dead class CRuntimeFunctionRefinementAllInOneMethod
refactored FSTGenComposerExtension
- build now makes use of super.run
- needed to change visibility of FSTGenComposer.compose(List) to protected to allow overriding
