Speedups

[temcdrm]

• You can save time by using -o=both from the command line, which generates the OpenDSS model, then the dictionaries and finally the GridLAB-D model. Because at least two apps need OpenDSS for the Y matrix, and most of the time is taken up in SPARQL queries, the time for model creation is nearly cut in half.
• The DistRegulator query used a UNION clause that performed poorly; it's now split into two queries. Other queries using UNION did not perform so poorly, so they were left along.
• You can use the -t=1 option from the command line, or call the function with bTiming=true, to get SPARQL query times logged to console.
• Scripts were updated for case sensitivities on Linux, and to use a newly-archived version of the EPRI DPV J1 feeder.
• The transactive feeder name is now kept in source.
• Enhanced the feeder plot utility under taxonomy subdirectory.
• Updated the documentation.
• Resolved issue 1150 with a table of models on the main readme page.
