Parse AM Constants to get keys:value for Dialog

Takes the AlarmManager csv string and parsees it for key:value
pairs. These key value pairs are then used to fill in information that
the DialogFragment class needs to display information. An ArrayMap is
used to initialize and store a key and the values associated with it
through a data object class. This data can be retrived in updated by
providing only a key.
