bringing in diff-lcs
pending specs for some diff features
starting to implement bits of the spec
not returning anything or running analysis if there were no changes
sneaking towards being able to tell moved things from deleted things
refactoring
storing the relative position of each TimeBlock and BusinessItem
dropping the time alteration idea
simplifying
returning change info for new time blocks
basic diff processing of a deleted time_block
refactored spec; basic "modified" test
including business_item data when diffing deletions
slightly more sensible outline for business_item comparisons
making it a bit easier to read
wiring up new business items
pending specs for more business_item functionality
its not it's, argh
added failing spec for the "Lord Freud 6" problem
