=============================================================
Functionality Provided
=============================================================
Supports the following file operations:
	-Read
	-Read directory
	-Open
	-Close
	-Create
	-Ioctl calls:
		-Change level
		-Mount point location

=============================================================
Setup Instructions
=============================================================
Use instal the linux kernel v3.8.5 and run it
Run make Within context_sensitive_fs/
Run load_scripts/load.sh
Run monitor/run.py
Then you can use the file system mounted at /mnt


=============================================================
Expected Results (assumes everything is already setup)
=============================================================
1) Issue create (call touch)
	-See new directory entry with name provided and 0 size
	-Behind the scenes there will be two other files one with a :0 appended and the other with :1
2) Issue open and read (call cat, open file through program, etc)
	-See contents of file (empty if nothing there)
	-Behind the scenes, the process is added to a list of things to send sigkill to
3) Issue change level ioctl (insert/remove usb will do this if the context monitor is running)
	-Any process that opened a file will be killed
	-Assuming writes work
		-If moved to level 1, all previous data and perhaps more data will now be visible
		-If moved to level 0, anything exclusive to 1 will no longer be visible
3) Issue read directory (call ls)
	-shows only the dummy files and not the files that describe the levels
	-shows the correct size and access times
4) Issue write (add something using a program)
	-Doesn't work yet, but if it did:
	-Under level 0:
		-Updates the file (can read it again and see the changes still there)
		-Updates the metadata (size, times, etc)
		-Marks the blocks in level 1
		-If read from level 1, would show the updates
	-Under level 1:
		-Updates the file (can read it again and see the changes still there)
		-Updates the metadata (size, times, etc)
		-Doesn't do anything to level 0 unless you are modiffing a shared block, in which case it allocs a new block for the new content
		-If read from level 0, would not show the updates
