         Quartus fitter may have introduced some one-LUTs in the post-fit netlist that makes it harder for VPR to place and route.

 	Change Log:
+		- Srivatsan Srinivasan, September 2021:
+			- removed the function parameters "original_num_nodes" and "nodes". These values can be from the "module" parameter and are now assigned internally within this function.
 		- Srivatsan Srinivasan, August 2021:
 			- Moved the incrementing of the "oneluts_elim" variable to this fuction from the "remove_node" function. The purpose of this change was to localise any vairable attached to removing one lut nodes within this function. Additionally, now the "remove_node" function is generalized and is not limited to be only used by "remove_one_lut_nodes".
