added cache.c and cache.h
buffer cache now working for previous tests except for page parallel. Still need to get rid of bounce variables and implement read ahead(don't know yet how we'll get the next sector)
got bounce variables fixed. come at me
didn't actually replace bounce as it fails all paging tests currently. Will look into it. Reverted back to bounce implementation in the mean time
cache is working fully except that it requires the bounce buffer still. Working on that
byte_to_sector written and changed inode structs
Merge remote-tracking branch 'origin/ben_filesys' into ralph_dev
Changed the creation and the freeing process. Still need to do read and write
