Convert a grayscale image to ASCII

<<http://www.alfnie.com/software/cameraman.jpg>>

*Inputs:*

* *img*: Grayscale image (a matrix of values between 0 and 1)
* *chars*: Char array of valid ascii characters
* *bitmap*: Grayscale images of each valid ascii character (3d matrix with size Height x Width x N, and with values between 0 and 1)

*Output:*

Bin the original image _img_ into segments of size _Height x Width_, and find the best matching ascii character for each bin (minimizing the euclidean distance between each bin grayscale values and the matching character grayscale values).

Return the fitted ascii image: a matrix of characters in *chars* that, when displayed, approximates the image *img*.

*note*: for an appropriate display the display font needs to be monospace. If a char image does not fit within the command window, you may try the following to display it on a figure:

fontsize=6;
 figure;
 uicontrol('style','text','units','norm','position',[0,0,1,1],'string',str,...
 'fontweight','bold','horizontalalignment','left','fontname','monospaced',...
 'foregroundcolor','k','backgroundcolor','w','fontsize',fontsize);

and edit the value _fontsize_ so that the image fits within the figure.
