class ShareSavTraversals {
HMP services will receive a request with User name and SAV name as input.
User is associated at Level 3 in the Share Hierarchy.
If the user is attached at level 3 then get the all the share node Ids that user has access.
Since the SAV's attached at level 6 in the Share Hierarchy, check for the given SAV Name input name at level 6 in the share node attributes.
If SAV Name matches with SAV Name Attribute at the Level 6 Node then return the corresponding SAV ID to the called environment(Response).
