API to resolve resources based on optional 'occurrence' options

User can specificy options to get firstN, lastN and by the Range
(begin, end) of 'occurrence' to get the resolutions. If no options
are specified, all the resolutions are returned in decending
oder (latest on top).

Map of resolutions are returned with 'occurrence' as the key to the
corresponding list of resolutions.
