 * Finds or creates an operation for conversion or transformation between two coordinate reference systems.

 * widest intersection between its {@linkplain AbstractCoordinateOperation#getDomainOfValidity() domain of
 * validity} and the {@linkplain CoordinateOperationContext#getAreaOfInterest() area of interest} is returned.
 *
 * <p>The default implementation performs the following steps:</p>
 * <ul>
 *   <li>If a coordinate operation has been previously cached for the given CRS and context, return it.</li>
 *   <li>Otherwise:
 *     <ol>
 *       <li>Invoke {@link #createOperationFinder(CoordinateOperationAuthorityFactory, CoordinateOperationContext)}.</li>
 *       <li>Invoke {@link CoordinateOperationFinder#createOperation(CoordinateReferenceSystem, CoordinateReferenceSystem)}
 *           on the object returned by the previous step.</li>
 *       <li>Cache the result, then return it.</li>
 *     </ol>
 *   </li>
 * </ul>
 *
 * Subclasses can override {@link #createOperationFinder createOperationFinder(…)} if they need more control on
 * the way coordinate operations are inferred.
 *
 * @param  sourceCRS  input coordinate reference system.
 * @param  targetCRS  output coordinate reference system.
 * @param  context    area of interest and desired accuracy, or {@code null}.
 * @return a coordinate operation from {@code sourceCRS} to {@code targetCRS}.
 * @throws OperationNotFoundException if no operation path was found from {@code sourceCRS} to {@code targetCRS}.
 * @throws FactoryException if the operation creation failed for some other reason.
