Bugs found during integration were fixed and minor code improvements were made such as using consts, const params, renaming members etc.
Using QList meant we need to know the port count in the constructor - which is difficult to know because StreamTiming is designed as a singleton
This singleton class will keep track of Ttag timing across all ports and GUIDs. A bunch of FIXMEs/TODOs are pending for this class implementation; also this class has not been hooked up to the rest of the code yet.
