0.3.0

• The Datum, Selection, and Sequence classes have been merged into a unified Query class
• Errors are now thrown for incorrect number of arguments
• Wrap any non-query arguments with r.expr(). This means nested queries are resolved before the action is performed!
• Type-related error messages match rethinkdbdash more often
• pluck and merge are now 100% bug-free
• without supports nested arrays (but not objects yet)
• default works with nested queries
• r.expr() now checks for undefined and imaginary numbers
• Fixed edge cases with update(null)
• Implement the catch method
• Add a Result class for reusing the result of a query via query.do()
