I figured out that only crucial problem for running this program is in the line #include equation_systems.h, since I commented out the other header files that were causing trouble and it didn't add any compiling errors.
equation_sysems.h is complaining about nullptr. Now I am thinking that either it is a compiling error or equation_systems.h needs to be modified in some way to work, do you have any other ideas of what the problem might be?
