EMST example

[xiaozxiong]

Hi, I want to use the EMST program of ArborX (described in your ICPP paper) as a baseline, but I didn't find any existed example in the project. So I need to write my own example following your examples?

@xiaozxiong So far, we have been using benchmarks/dbscan to run EMST. To run it, use

$ ./ArborX_Benchmark_DBSCAN.exe --algorithm mst --core-min-size 1 --binary --filename <file.arborx>

The file data format is described in the Data file format section of the README.md in that directory.

You are right, though, we should write an example. We would welcome your contribution if you end up writing your own before we do. It should be pretty straightforward, simply taking examples/dbscan and replacing DBSCAN calls with MST ones.
