Version 2.2.0
This release dramatically improves how phasing is done on UVData objects and adds support for multiple phase centers and non-sidereal phase centers. Reading and writing out data with multiple phase centers is supported for UVH5, UVFITS, MIR, and MIRIAD files. It also adds support for a filename attribute on UVData objects and support for getting and selecting data on UVData objects using LSTs.
Other improvements and bug fixes are detailed in the changelog.
