Features

• Created shims for warning and error handling
• Automatically load and unload shims alongside package calls.
• Added coverage tests to verify the presence of the handlers and for
  checking the contents of the error handler.

Special Thanks

This package exists in large part due to conversations or assistance from
the following folks:

• Dirk Eddelbuettel for starting the discussion
  on XKCD Comic 1185: Ineffective Sorts.
• Barry Rowlingson for the package name and
  remarks about functionality.
• Brodie Gaslam for pointing out
  addTaskCallback()
  as a way to create a warning handler and for a brief discussion on "call"
  objects.
• Joshua Ulrich for advise on incorporating
  the semi-documented last.warning
  object that R populates with warning messages.
