/**
* This tracks the current scope for an SSViewer instance. It has three goals:
* - Handle entering & leaving sub-scopes in loops and withs
* - Track Up and Top
* - (As a side effect) Inject data that needs to be available globally (used to live in ViewableData)
*
* In order to handle up, rather than tracking it using a tree, which would involve constructing new objects
* for each step, we use indexes into the itemStack (which already has to exist).
*
* Each item has three indexes associated with it
*
* - Pop. Which item should become the scope once the current scope is popped out of
* - Up. Which item is up from this item
* - Current. Which item is the first time this object has appeared in the stack
*
* We also keep the index of the current starting point for lookups. A lookup is a sequence of obj calls -
* when in a loop or with tag the end result becomes the new scope, but for injections, we throw away the lookup
* and revert back to the original scope once we've got the value we're after
*
