Now outputs to image file rather than to stdout. Image file much improved.

README.md

 I'm deliberately not randomizing the symbols. Sending the same input image should result in the same output image every time.
 
 TODO:
-* Accept image name on command line.
+* -Accept image name on command line.-
 * Change characters to symbols for ease of reading.
 * Expand number of symbols.
-* Create image from symbolized pixels instead of just printing to screen.
-* Add grid lines and edge labels to image.
-* Add legend to image, based on the `symbols` dictionary.
+* -Create image from symbolized pixels instead of just printing to screen.-
+* -Add grid lines and edge labels to image.-
+* -Add legend to image, based on the `symbols` dictionary.-
 * Correspond hex colors to floss colors, where possible.
 * (Maybe) add stitch count for each color.
 * (Maybe) add GUI.

stitchify.py

 	This tool assumes that 1px = 1 stitch.
