2. Run 'make' in both pagefault-test/ and matrix-multiply/, and insert the produced executables into the target VM

NOTE: COMPILED WITH GNU11

Testing:

1. pagefault-test

   Accepts 3 arguments:

    Arg 1: Number of threads to use
   
    Arg 2: Type of Access (0 - sequential, 1 - random, 2 - semi-random)
   
    Arg 3: Cache Parameter (0 - disable, 1 - enable)
   

   Ex: ./pagefault-test 4 0 1

   Runs the sequential access test on 4 threads, all with the software cache enabled

2. matrix-multiply:

   Accepts 2 arguments:

   Arg 1: Matrix Size
   
   Arg 2: Cache Parameter
   

   Ex: ./matrix-mult 1000 0
