Login/Sign Up Complete

Login/Sign Up Complete. Start on DataSelection & Store
Merge branch 'develop'
Add database partially implemented. Structure redone.

Needs to keep track of what user was using application before entering
database keys because I need to switch database from PDC database to
user’s database.
Changes due to 3/18/14 phone discussion

On login, project asks for keys the first time with username and
password for the database. If successful, keys are saved so that the
next login does not require the keys.

Adding information was done differently to handle only one database.
Class and parameter adding was also done differently. Bugs with the
“AddDatabase” window were fixed.

Coding restructured to suit changes. Back to the point the project was
at before changes to how login and the data would be handled.
