/*
* jQuery basic plugin "Content revealer"
*
* To use on a link reveal hided element with 'slideDown' animation, link
* emitter will be hided.
*
* Link 'href' is basically any valid DOM selector to element to reveal, but
* commonly a '#id' that match element id.
*
*
* HTML sample:
*
*   <a href="#sample-to-reveal" class="content-revealer">Read more</a>
*   ...
*   <div id="sample-to-reveal" class="content-to-reveal">Hello world!</div>
*
*
* You will have to hide '#sample-to-reveal' by yourself with CSS rule, plugin
* does not do that for you (and doing it from CSS is better than from JS).
*
*
* CSS sample:
*
* .content-to-reveal{
*     display: none;
* }
*
*
* Usage exemple:
*
*     $('.content-revealer').contentrevealer();
*
