IOTA: integration optimization, triage and analysis

IOTA is a user-friendly front end for the cctbx.xfel suite of serial diffraction data processing programs. It is comprised of three main modules:

 1. Raw image import, conversion, pre-processing and triage
 2. Image indexing and integration using cctbx.xfel modules (with optimization of spot-finding parameters)
 3. Analysis of the integrated dataset

These modules are united by a command-line interface and are run in sequence. The user can point IOTA towards a single diffraction image, a folder of images, a list of image paths or a modified script file. If no script file is supplied, IOTA will automatically generate reasonable defaults (currently optimized for a MARCCD detector, but also usable with Pilatus detectors).
