OPUS_Accumulator: new Plotting option, fixed UTM statistics

Recently I found a bug in the OPUS_Accumulator tool. I don't know that it would affect anyone in real life, however later in this message I will describe the contitions that triggered it. There is a link at the bottom of this message to the most recent OA version and if you use OA, you should update.

The intention of OA is to make looking at lots of OPUS reports based on the same point easier to compile. My assumption is everyone who uses OA is feeding 24-hour daily files from CORS sites into OPUS, then gathering the returned OPUS-Static results in a single folder and finally running OA. The .PRN output file includes an average result in DMS suitable for directly entering into an RTK base.

But it has been difficult to get a quick feel for how stable stations might be. I find myself plotting the UTM X, Y and ellipsoid heights over and over again in Excel.

You can now click a checkbox and OA will automatically generate a nice trend graph of all the of summarized data. A full description of the plot can be found here: [ OA_Plots ]:

These plots make it pretty easy to quickly watch CORS sites go bad. They also make it simple to visulaly evaluate trends, the range, standard deviation, skewness and (perhaps) kurtosis of a station's dailys.

The UTMX and UTMY statistical calculations may not have been initialized after the first run on a folder. So if you ran OA on a folder with 20 files, then ran it on a folder with 15 files, the last 5 files on the first folder would have contributed to the UTM X and Y summary statistics at the bottom of the column. The values listed for each file would be correct, however the statistics at the bottom of the column for the UTM X and Y would have been incorrect.

So to summarize: only affects OA runs after the first run of an invocation. Only affects UTMX and UTMY derrived statistics, tabulated values were correct.
