/**
*
* Does round trip testing by creating the oracle object, then decoding it.
*
* These tests do not include insert / delete / select operations.
*
* NOTE: This test does require a precision to be used during the comparison,
* as points are rounded somewhat when creating the oracle struct.
* (One less decimal than a java double).
*
* NOTE: The points may be re-ordered during these tests.
