Exception when "array source" has single value

[mikekucera]

I triggered this with an EnrichmentMap network...
I went to the edge table, selected column of type double, and set the entire column to the same value (in this case 1.0).
Then open the MCL Cluster settings dialog, and selected that coumn for Array Source.
The following exception appears in the log...

java.lang.IllegalArgumentException: Upper value is less than or equal to lower value

The BoundedDouble tunable does not accept the upper and lower bound to be the same value.
