Create a temporary object holder

## What shortcoming will this fix cover
This will allow users to generate objects that aren't necessarily mapped directly into the overall Pojo that is being generated.

## Why its important to make this change
Currently, the MorphLimiter can only be used against a single value/limiter. By having some form of generated state that is kept in the generator object, it would allow for an unrelated object to be created that is then used everywhere within the the generator for morph/correlation.

## How much time I would invest in making this patch (if I had the free time to do it)
3 hours

Start by tracing MorphLimiter and the generator object, since the issue names these as the current limitation and proposed state location. Define how an unrelated temporary object is generated and reused for morph/correlation, then verify that it works without requiring the object to map directly into the generated POJO.
