/**
* This is used for switching the type of a ValueNode within a given context. Basically, a
* switch is made between valueNode and newValueNode, but their types are different.
* Consequently, other valueNodes may be modified.
*
* <p>For example:
*
* <p>Let's say you have "add 1 2", where 1, 2 are of type Integer and are represented by
* ValueNodes, then to switch '1' to '1.0' (a Double), you must switch '2' to '2.0' to avoid
* type clashes.
*
* <p>This method will handle the switching of the associated types within a type context, so it
* should so if you pass 1, 1.0 it'll convert 2 to 2.0 .
*
* <p>Note that you are able to pass in '5.0' as the new value if you'd like.
*
* @param oldValueNode your original ValueNode
* @param newValueNode the valueNode that you want to arrive at
