This is the re-submission for Project 2.

For Part 1:
test_document.txt and test_document_nozoinks.txt were used to test the effectiveness of part1. 
the "test" executable (built from test.c) automatically tests with those files. 

How to Build Program:
To build the program, simply "make". After making it, type in "sudo insmod ancestry_kernel_module.ko" in order to satisfy Part 2. 
For part 1 type in "sudo insmod module_combined.ko".

How to Test Program:
Build the procAncenstry tool by typing "gcc -o procAncestry procAncestry.c" and then run the program and supply a PID as a command line argument. Below is an example of our procAncestry executable. 

Evidence of testing and Logs:

Example execution of our procAncestry executable:

./procAncestry 1411
