Code Review for database update

This is unfinished and there is commented out code in MAIN that I will
remove - however it makes a good example of what is going on. this
should provide enough for you guys to test with and finish wiring up the bits - Jay your classes work and I left comments in on what is missing from stock.java - I will be finishing this part tomorrow night. 2 sets of logic and queries that are already written need to be wired up.to make sure it functions.
