/**
* GlobalSettings encapsulates SystemProperties, since the codegen mechanism heavily relies on a stable,
* non-changing System Property Basis. Using plain System.(get|set|clear)Property raises Race-Conditions in combination
* with Code, that uses System.setProperties (e.g. maven-surefire-plugin).
*
* This provides a set of properties specific to the executing thread, such that the generator may not modify system properties
* consumed by other threads.
