Allow for multiple PIs & multiple projects on a grant

[nihiliad]

The following code in CONTRACT_PROJECTID_XREF_VW limits us to only one project per contract, when in reality there may be many projects per contract:

SELECT contract_num, business_unit_pc, project_id 
FROM FS_PS_GM_AWD_PROJT_VW@dweprd proj
WHERE proj.project_id = (
  SELECT MIN(proj2.project_id)  -- AHA! This limits us to only one project per award/grant. Why?!
  FROM FS_PS_GM_AWD_PROJT_VW@dweprd proj2
  WHERE proj2.contract_num = proj.contract_num 
  AND proj2.project_id <= proj.project_id
);

Also this, from Andy Herzog, an example which excluded PI Heather Nelson (1417996) from a grant:

Multiple projects per grant?

• Contract number: CON000000103852
• Three projects associated with this grant
