Version 2.0 - Integrated R5.6 and pre-R5.6 compatibility

This release contains an update to ReadPhilips allowing it to be used to read both R5.6 and pre-R5.6 data. In addition, for R5.6 data, a new node called ExpandSpiralCoords has been added — you'll find this under the sprial heading in the philips library. The spparams output of ReadPhilips contains coordinates for a single spiral arm when reading RAW/LAB/SIN data — ExpandSpiralCoords takes this as its input and generates the full coordinates for all arms in a given scan.

To install these nodes, download the appropriate ZIP archive for your GPI installation (OS and Python version) and unzip the enclosed philips folder into your GPI node library (usually ~/gpi).
