Comparison of 2d and 3d

This is an image from Andy's long 2d runs on jaguar; build date: 08/06/08; resoultion: 2.5cm
This is a slice through the center of the domain for a 3d run on jaguar; build date: 09/11/08; resolution 10cm.
This is a recent 2d run at the same resolution as the above 3d run; build date: 09/17/08; resolution 10cm.
This is an image from an old 2d run on homer ; build date: 07/02/08; resolution 10cm.

These two images are probably not the best for a comparison. I havn't looked through the changelogs but I imagine there many things different between the two build dates.

I've found out that the 3d analysis routines I have written are very slow when dealing with such resolution. As such, I'm going to rewrite them to allow the user to specify which variable(s) to perform averaging on - as it is now, averaging is done for all variables in the plotfile. Furthermore, I'm going to try to tweak the averaging procedure to be a bit faster.
