 *	This is a special type of variable that can be used to connect to a variable anywhere in the level sequence.
 *	When play begins, it will search up parent sequences to find a variable of the corresponding type whose name matches FindVarName and connect to it.
 *	This makes it easy to have one instance of a variable that is used in many places throughout sequences without complex wiring through many layers.
 *	Similar to a global variable in C++.
