koennecke 86e246416b - Added bridge functions to histmemsec to make it look more like histmem
- Modifed many modules using histmem to work also with histmemsec
- Extended tasker with task names and task groups
- There is a new taskobj which allows to list tasks and to interact with them.
- Task now supports running Tcl functions as tasks
- There is a new experimental sctcomtask module which allows to define communication
  tasks against a scriptcontext. This is a new feature which should facilitate
  writing sequential scripts using asynchronous communication.
- A fix to make spss7 work when there are no switches
- ORION support for single X. TRICS measures crystals hanging down, ORION
  standing up
