v0.1.1

xray 0.1.1 is a bug-fix release that includes changes that should be almost
entirely backwards compatible with v0.1:

• Python 3 support (#53)
• Required numpy version relaxed to 1.7 (#129)
• Return numpy.datetime64 arrays for non-standard calendars (#126)
• Support for opening datasets associated with NetCDF4 groups (#127)
• Bug-fixes for concatenating datetime arrays (#134)

Special thanks to new contributors Thomas Kluyver, Joe Hamman and Alistair
Miles.
