* Convert Outer Join.
* Converting joins can ve very complex when multiple tables/keys are involved.
* The main scenarios supported are two tables with multiple key columns
* and multiple tables with single key columns.
* <pre>
* SELECT a.Col1, b.Col2 FROM tableA a, tableB b WHERE a.ID=b.ID(+)
* => SELECT a.Col1, b.Col2 FROM tableA a LEFT OUTER JOIN tableB b ON (a.ID=b.ID)
*
* SELECT a.Col1, b.Col2 FROM tableA a, tableB b WHERE a.ID(+)=b.ID
* => SELECT a.Col1, b.Col2 FROM tableA a RIGHT OUTER JOIN tableB b ON (a.ID=b.ID)
* Assumptions:
* - No outer joins in sub queries (ignores sub-queries)
* - OR condition ignored (not sure what to do, should not happen)
* Limitations:
* - Parameters for outer joins must be first - as sequence of parameters changes
* </pre>
