Overview

Used by Rtml::ReverseEngineering::Simulator to track the value of a variable. Attempts to build a logical value by processing the setvar’s :lo, :op and :ro attributes. References to other variables are automatically resolved. References to nonexistent values assume built-in variables and assign generic values to them.

Implements a #== method to see if one variable’s value is equal to another’s, though this may not always be accurate.
