Deregistering a histogram via its name causes a memory corruption (often
resulting in a crash). The problem was that deReg(string) kept checking
the histogram list size while the list is actually being deleted in the
last call to deReg(TObject*).

Also improved the unit test coverage for this case.

- if the property 'TopAlg' is set, then IHiveDataBroker is used
  to obtain the neccessary sequence of algorithms for each entry.
  These sequences are then coalesced and used

- introduce an interface which, given a collection of DataObjID,
  returns a range of pointer to Algorithms which, after executed
  (in the order returned!) guarantee (in absence of processing errors)
  the existence of all entries in the specified DataObjID collection.
- introduce an interface which, given a (control flow) algorithm name
  returns a range of pointer to Algorithms which, after executed
  (in the order returned!) guarantee (in absence of processing errors)
  result in execution of the (control flow) algorithm

- add possibility to dump data flow to a .dot file, which can be
  processed by 'dot' (part of GraphViz)
- add a few const/mutable to indicate thread safety
- tweak printout a bit...

- remove unneccessary code
