- Register af3.timing / Wcet and Period annotations to tasks. Wcet is the assumed WCET of a Task (independent of the ExecutionUnit to which it mapped)
- Add TaskWcetTable that allows to specify the WCET for (Task,ExecutionUnit) pairs.
  - For now, the values can be edited in the annotation view only
  - TODO: Integrated task WCET table as secondary TaskArchitecture editor
