Allow Gesture Recognizer To Function Simultaneously With Other GRs

This modification ensures that apps depending upon this library which
have other gesture recognizers in use during the display of
BEMSimpleLineGraphView will be able to utilize delegate methods
-lineGraph:didTouchGraphWithClosestIndex: and
-lineGraph:didReleaseTouchFromGraphWithClosestIndex:

Without responding to the UIGestureRecognizer delegate method changes
contained in this commit, the BEMSimpleLineGraphView delegate methods
are never called.
