<p>A simple MongoDB output node. Stores the <b>msg</b> object in a chosen collection.</p>
<p>By default MongoDB creates an <i>_id</i> property as the primary key - so repeated injections of the same <b>msg</b> will result in many database entries.</p>
<p>If this is NOT the desired behaviour - ie you want repeated entries to overwrite, then you must set the <b>msg._id</b> property to be a constant by the use of a previous function node.</p>
<p>This could be a unique constant or you could create one based on some other msg property.</p>
