A number of utility functions for working with the Corona SDK. Currently they're scattered all over my projects, and I'll be adding them to the repository as I think of them/rediscover them.

main.lua contains usage examples.

• hasEventListener(self, event, callback)

  Check whether self has a listener for event. The optional callback parameter lets you check for a specific event listener, since multiple listeners can be added for a single event.

• shuffleTable(t)

  Shuffles the elements of t (an indexed array). Shuffling is done in-place (i.e. does not return a new table).
