Nano Manual Config With Overlapping Spectral Ranges

[chaneylc]

The nano device allows users to create scans that have overlapping spectral ranges.
E.g: section 1 from 900-1700 and section 2 from 900-1700

This will create a single line graph in the scan list fragment that connects from the first section 1700 to the second section 900, which is a bit odd. Possible solutions are to update the graphing code to detect and split this into two different series or alternatively (worse solution imo) disallow this type of config in the creator.
