3.0.3

This code collects Tweets in an area around Galway, Ireland. The one thing to notice here (and something that baffled me for a while) is that while it returns (latitude, longitude), the bounding box is defined as {{longitude1,latitude1},{longitude2,latitude2}} as answered here

This is using Twitter4j 3.0.3 Core and Stream.
