* N°4789 - Parse datamodel module.xxx.php files instead of interpreting them - refactoring all in a dedicated service first * N°4789 - fix broken setup + tests * N°4789 - replace legacy eval by module file parsing * N°4789 - handle constants and if conditional structures * N°4789 - compute boolean expressions * N°4789 - make autoselect and dependencies work as well * cleanup * N°4789 - fix BeforeWritingConfig calls during setup * N°4789 - refactor and split in ModuleDiscoveryEvaluationService + handle ModuleInstallerAPI methods calls during setup * N°4789 - PR review changes with Romain * PR review + code cleanup + added usecases and test cover * temp evaluation work * replace eval by iTop custom evaluation classes * move PhpParser/Evaluation classes in a specific namespave + composer dumpautoload * fix broken setup * fix broken setup * complete Evaluators list + autoload * cleanup useless testing resources * cleanup + replace last eval call in VariableEvaluator * fix few Evaluators code * enhance nikic evaluators + test with/without nikic lib * Evaluator fixes/enhancements + tests * bump to nikic fork temporarly * bump nikic-parser fork + use only nikic fork evaluation + cleanup itop redondant evaluators * review with Romain: use distinct whitelists in setup time/runtime + move ModuleFileParser internal logic into ModuleFileReader * PhpExpressionEvaluator used via constructor and not as a service * dumpautoload again after rebase
