Detailed Description

Abstract class for a nesting operations in a loop-nest.

In the following example, the nested operation of "IF C1" is "IF C2":

QUERY
 ...
  IF C1
   IF C2
    ...

TODO (b-scholz): profile text is awkward; perhaps there is a better way of storing profile information for RAM operations since it is not always used for all RAM operations.
