v0.2.2

• Adds an undocumented (for now) MeasurementSets module for creating CasaCore measurement sets
• Fix some errors in the way column shapes are computed

v0.2.1

• Arithmetic on Direction produces an UnnormalizedDirection, which can be converted back to a
  regular normalized Direction. This allows intermediate operations to be unnormalized before
  explicitly normalizing at the last step.
• Experimental (unexported) support for rotation matrices.
• Julia will no longer crash when trying to operate on a closed table. This used to occur because
  the C++ code throws an exception. Now Julia will throw an exception instead.

v0.2.0

• Package reorganization for compatibilitiy with Julia v0.6.
• Documentation improvements.
• Array keywords are now allowed.
• Subtable keywords are functional again.
• Some arithmetic operations on measures are now defined.
