Minor change

Add cast to int when getting selectedSegmentIndex to save. Minor adjustments to save patientID during signup.
Adjust PCADefinitions use

Change #includes of PCADefinitions to #imports. Move showAlert methods to PCADefinitions to avoid duplication. Can now be called from anywhere. In Login and Signup, add variable referencing the AppDelegate. Add instance variable of PCADefinitions to AppDelegate so showAlerts can be called.
Adjust UI element CGRectMake size creation

Create ints to define offsets and heights, widths, etc. for UI elements and replace most hardcoded values.
Eliminate some todos and add some error types.
Major update — add ability to save esasEntry custom class?

Add NSMutableDictionary property on main controller to store key pairs as the user enters symptoms. At the end, this dictionary is loaded into an esasEntry which (I think…) is saved to the backend. No good way to verify this at this point—querying comes next. Additional changes:

Some refactoring of switch statements to use typedefs from Definitions.h
Error handling when no segment is selected on radio screens
