App is functional for multiple clients/users (client, parent, caregiver/teacher) with variable levels of access:
-Adding/deleting/editing events is an admin function that may be passcode-protected
-Calendar may be accessed/updated from multiple devices (communication between clients/parents/caregivers)
-App will hold multiple calendars for multiple users (such as for a classroom)
LONG-TERM GOAL: app collects and exports data from/to multiple users
