Resizer constants not exported

In 71bf017#src/utils/Resizer.js the Resizer docs were updated to say to use the DIRECTION_* and POSITION_* constants, but they aren't actually exported.

@jbalsas interested in taking this one? Seems like an easy fix.

@alltom Currently implemented Directions and Positions have been exported for Resizer. Thanks for reporting it!
