Adding parser function to Simulator.CPP and updating PCB class

put the parser function in the sumulator.cpp.
dunno where else to put it. if we need to, we can change the location.

Also added some more getters/setters and constructors for the
processcontrolblock class.
process text file

for testing purposes, we can use this text file.
you can add as many processes and as many cpu bursts as needed.
BUT must be in the correct format. make sure TNCPU indicates actual
number of total CPU bursts, the process finishes with a CPU burst, and
no white spaces at the end of the text file :)
fixes issue #1
changing location of process.txt file

putting it in /test
removing libraries that are already included

libraries are linked. duhhh
as per Ricky's request

initializing all values
Spacing changes
simplifying parser code to read integers directly

still need the string variable though to get rid of the first header
line in the text file.
