void setDepth(Instruction instr, int depth) {
		depthMap.add(instr.getMinAddress(), depth);
	}
Construct a new CallDepthChangeInfo object.
Using this constructor will track the stack depth at the start/end of each instruction.

@param function function to examine
@param restrictSet set of addresses to restrict flow flowing to.
@param frameReg register that is to have it's depth(value) change tracked
@param monitor monitor used to cancel the operation

@throws CancelledException
