Error when user doesn't have enough access

[pgonzaleznetwork]

the listMetdata() call fails when the user is not an admin. Need to do some research to see what the user sees in the UI when this is thrown. Potentially we need to catch the error and modify it to return a more user friendly message i.e

You must have a system admin profile in order to use HappySoup.io. You are missing the ModifyAllData or ModifyMetadata permissions
