Add visualizer.

Lasciate ogni speranza voi ch'entrate:
    I am the bone of my javascript
    DOM is my body and JQuery is my blood
    I have created over a thousand lines
    Unknown to death
    Nor known to life
    Have withstood pain to create many functions
    Yet those hands shall never type anything
    So, as I pray, Unlimited Openlayers Works
