Makefile

## How to use this Makefile
## You should not have to modify anything except the OBJS variable
## 	by adding .o file names if you have more .cpp/.hpp files.

# STUDENT TODO: Append to this list if you have more files to compile
# E.g., if you create the files `custom.cpp` and `custom.hpp`, add 'custom.o' to the list below. 
# You should also add them to the `main.o` dependancy list (after `tasks.hpp`)
