Export information needed by the tumor registry

[Nicklas Nordborg]

The current information is that we need a comma-separated file with personal number, operation date and site. The list should be generated for a given month at a time.

The main query should find all Specimen and NoSpecimen items with a 'Created' date falling in the selected month. It should only exclude core biopsy items and other items annotated with the BiopsyType annotation (unless the value is SpecimenSurgery).

Once we have this list the patient can be found by loading the parent of the parent (eg. Specimen->Case->Patient) and then the personal number can be found.

The site can be found by inspecting the name of the specimen item.

Duplicates (eg. bilateral cases) should be removed from the list.
