Added the script to create the CHARM database. This *should* work to create our databases.

Two notes:
	- I was actually using a rather embarassing number of reserved words as variable names, so that is why a number of the names are not what they were in the high-level design. None of the name changes affect functionality, though.
	- ALSO, we have one rather squirrely design element, namely the use of Date as a primary key in a couple of different contexts. This is something we'll have to be careful with as we go along creating our scripts.
Changed a couple names for readability
