+/**
+ * A class for generating unique IDs, in two possible ways.
+ * 
+ * Almost every XMI element contains a UID. This class can generate both globally
+ * unique IDs, and deterministic unique IDs (ie. the IDs are the same every time the
+ * parser is run again). We need such deterministic IDs because of the PHP_UML test
+ * suite, which would report errors otherwise (because of different IDs !)
+ * You select which one by setting the boolean property $determinisic to true/false
