Convenient != Efficient

OpenCV has some convienent data storage functions for all of its crazy datatypes.  I’m thankful that I don’t have to worry about reading and writing CvMat, IplImage, and so on.

However, the file size leaves something to be desired.  It writes everything as text in XML.  As a result, a float increases in size by 400%.  AWESOME!  And that’s not even counting all of the XML overhead.

I’m thinking I might have to tweak this at some point…
