0002e899f8 Fix a few more issues with the Haar importer
- It imports and creates binary files that don't crash the cam
- No tracking yet
- Number of features from rects is different than number of features from weakClassifiers for some reason..

c30f0616cb Changes to make Haar importer work with new XML format
- Still seems to create buggy data, camera starts to blink blue/white after a while when trying to use the cascade, no tracking at all
- Only the actual conversion part has the changes, info and header not
- Few info on format, limited info here: http://answers.opencv.org/question/8418/explanation-of-cascadexml-in-a-haar-classifier/

5f4e690fa1 Add find circles.
Now you can find circles with your OpenMV Cam! The alrogithm can eek out
about 7 FPS on a 160x120 image which is quite impressive given how
computationally expensive circle finding is...

* Angle averaging done correctly using sin/cos now.
* Unspecfied color bounds default to least restrictive instead of most
restrictive.

cd4ad0dff3 Add linear regression
For easy line following mainly. In non-robust mode the line is computed
using least squares. In robust mode the line is computed using the
Theil-Sen median of slopes method. We do not use the Siegel Median of
Medians operation because it costs more CPU time... but, more
importantly there's no way to improve the centroid estimate so even if
the slope is more robust the line will be drawn in the wrong place.

long alignment now or in the future.

Add Image Writer/Reader

dc6ab59cfd Add Image Writer/Reader
These two new classes allow you to record image data for later viewing
at the same speed the image data was recorded. Unlike GIF/MJPEG the
image data is stored on the file system completely uncompressed in
native frame buffer format making super fast reading and writing
possible. Recording VGA Grayscale at ~13 FPS is possible along with
playing it back. (That's about 30 Mb/s folks).

...

The motivation for writing these scripts is so that you can record video
of something like a line following track, take that video home, and work
on computer vision algorithms for that data.

These classes should make it a lot easier to use the camera at home now.

f9e124f8cd Refactor framebuffer
Moved structs along with image copying code from sensor into
framebuffer.c so that we can use the new copy_fb_to_jpeg_fb() function
in the image library for methods with "copy_to_fb" so that they update
the IDE preview when called.

Also, I noticed that the MAIN_FB_SIZE() value is not calculated
correctly in all cases. Will fix later. Trying to keep this commit clean
for just the refactoring.

All changes have been tested. Too.
