QGIS Plugin Scripting: Revisited

I learned, rather hurriedly, how to script QGIS plugins for a class.  I came away unimpressed with the class hierarchy (I got lost and certain methods I needed seemed misplaced and therefore hard to find).

But now that QGIS alone is becoming a viable replacement for other software, I'm motivated to try scripting plugins again.

So I'll be taking a look at moving over the apparent dip script and cross section script to the QGIS interface.  If all goes well, I'll actually have a nice way to distribute them via the QGIS plugin repository.
