| Purpose of this library is to make some of the unary outer aggregate operator more efficient. |
| Today these operators are being handled through common operations. |
| This library will expand per need and priority to include these operators through this support. |
| To begin with, first operator being handled is unary aggregate for less than (<), rowsum operation. |
| Other list will be added soon are rowsum on >, <=, >=, ==, and != operation.</div> |
