New JavaScript cryptogram helper

The first homework problem in my crpytography class was to break a cryptogram. After looking at the other cryptogram helpers on the web, I created the JavaScript Cryptogram Helper. It lets you paste cryptograms, highlights all instances of the selected letter in blue, and shows a table with letter frequencies to facilitate frequency analysis. The UI was inspired by Teppo Pihlajamäki's Flash cryptogram game.

    I’m not sure why I just spent the last 15 minutes doing your homework. (No doubt if I had been in class, this would have taken longer.) The helper helped — nice little script.
