subplot views

I was actually thinking through how you would automate a floating inset subplot that shows a zoomed in area. Not hard to do manually with Plots, but might be tricky to generalize

i had a quick thought about the floating subplot thing... it might be nice to implement a "subplot view"... basically a wrapper around another subplot, which inherits all the data and attributes from the wrapped subplot, but with optional overrides
then you could create an inset floating subplot that is a zoomed-in view with one easy line of code
i think that's pretty straightforward to implement... the only thing is that I might need to add an AbstractSubplot in a few places
