Make a wrapper for SDK7 eval

[dalkia]

A particular scene (Rapture, -89,-64) was not loading because a global var was required by the scene code. That was fixed by adding the var on this PR

But that may occur on any given scene that requires a global var not defined. On the previous runtime, this was managed by using a proxy-like architecture.

We should see if we can do the same wrapper, and test its functionality accordingly
