Fix for directly invoking report generation
Refactored drift image generation to distinct functions.  Added readouts for max drift, fastest tile, min drift, to SerialEM Log class.
Added an image showing drift based on tiles location in the grid to the report
Updates for report generator that builds HTML from a dictionary.  Code unused.
Revamp of how HTML reports are assembled for a better presentation
Added query to pipeline to include notes in reports
Notes elements now use resource element.  This means they have a path attribute.
Added SerialEM Version and Capture date to report webpage.
