Hi @cordosvictor thanks for your efforts!

personally I think that gesture detection should not be part of this library at all, because there is the panresponder and plenty of other libraries for react-native for that.

rationale: once we add android support, we will have to mimic the ios gesture detection or drop support for this feature, while panresponder has already solved that problem.
