persistent-memory

Add unit tests to ensure features of SplitFS, such as logging, are working correctly. These would supplement current higher-level checks for correctness.

I need to create tests that verify the implementation of features provided by PMAT.

• Verification under segmentation fault
• Verification under failure
• Verification under success
• Testing persistence of certain address
• Unregistering and registering persistent memory
• Verification that has an infinite loop (I.E tests implementation of #3)
• Tests transien
