// myProfileStatus provides functions to check if a user's profile is active on the network

package myProfileStatus

// For a profile to be active, multiple conditions must be met:
//	1. User's identity is funded
//	2. User's broadcast profile exists (the user has uploaded their profile to the network)
//	3. User's broadcast profile is funded (if profileType == "Mate")
//	4. User's broadcast profile is not disabled
//		A disabled profile will exist on the network until the identity's balance expires, or the maximum profile existence time has passed
//	5. User's broadcast profile Disabled status matches their local profile.
