[Beam Analysis plugin] Needs to differentiate between depth dose and profile scans

What steps will reproduce the problem?
1. Add a profile (inplane or crossplane) to a plot window.
2. Add a depth dose curve to that same plot window

What is the expected output? What do you see instead?

It doesn't make sense for a depth dose and profile to be overlayed.  There
needs to be some mechanism to keep this from happening.  Either a new plot
window needs to be opened, or an existing plot window that has the same
type of scan needs to be used.  I would suggest opening a new plot window,
otherwise it will be complicated if multiple plot windows are already open.
