Updating search to use character vector rather than named list.
Minor changes and fixes to pass tests - details in notes.

error reporting, existingElements/existingMetrics now working, segments
working for multiple report suites (was broken when no segments were
available for one of them, e.g. ASI slots), renamed call to
GetSuccessEvents to GetEvents (adobe changed this), changed selected to
apply to first element rather than requiring a named list.
Built GetUsageLog
Built GetQueue
Fixes to pathing and fallout parsing, adding CancelReport
