Details:

I've added an initial imfindcircles. It currently does the following:

Runs a canny edge detection to transform circles into rings
Creates a kernel image of the ring, one pixel wide, using the bwmorph command
Runs a matrix convolve2 function to populate the accumulator

All of these should be consistent with the Hough transform method that other
packages currently use, though their implementation seems to differ slightly.

Optionally, this will plot images with detected circles.

This will return an array of circle centers, as well as the detected radii and
confidence.
