Removed references to CollectedSession, which turns out didn't work the way I had expected. Added context manager support to DynectSessions
Switched record filtering over from get_all_records_by_type to get_all_records. Apparently get_all_records_by_type doesn't behave the way I was hoping it would and behaves more similarly to get_any_records, where it get's all records at a specific node, not throughout the entire zone.
Removed unused import
