Detailed Description

A string of return_superedge pointers, representing a call stack
at a program point.

This is used to ensure that we generate interprocedurally valid paths
i.e. that we return to the same callsite that called us.

The class stores returning calls ( which may be represented by a
returning superedge ). We do so because this is what we need to compare
against.

Instances of call_string are consolidated by the region_model_manager,
which effectively owns them: it owns the root/empty call_string, and each
call_string instance tracks its children, lazily creating them on demand,
so that the call_string instances form a tree-like hierarchy in memory.
