conjured value
Sometimes the return value of a comparison operator call is
`UnkownVal`. Since no assumptions can be made on `UnknownVal`,
this leeds to keeping impossible execution paths in the
exploded graph resulting in poor performance and false
positives. To overcome this we replace unknown results of
iterator comparisons by conjured symbols.

when printing the Program State
Debugging the Iterator Modeling checker or any of the iterator checkers
is difficult without being able to see the relations between the
iterator variables and their abstract positions, as well as the abstract
symbols denoting the begin and the end of the container.
This patch adds the checker-specific part of the Program State printing
to the Iterator Modeling checker.

actual checkers
A monolithic checker class is hard to maintain. This patch splits it up
into a modeling part, the three checkers and a debug checker. The common
functions are moved into a library.
