Marie&Aneeshe's work. work left for Christine/Chloe

I wrote the whole INode but 2 methods (read and write) left for Christine and Chloe.

Aneesh provided some methods that concern the block device; these methods that aren't part of INode but are integral to see whether INode actually works. Right now, I just put them all together to compile and generate the beautiful INode.asm that you guys can all see.

P.S. I need someone to allocate me RamSpace (memAlloc), as well as Patrick/Dan to do block_alloc.
P.P.S. Hit me up if you have q's.
