$Id$

This is a simple helper module to facilitate efficient retrieval of a single
quote from among those quotes which are visible to the anonymous user.  This
is useful for showing a single random quote somewhere on the page, without
the overhead associated with "order by RAND()".

The two functions intended to be used by other modules are as follows:

/**
 * Returns the nid of a randomly selected quote.
 */
function randomquote_nid()

/**
 * Returns a randomly-selected quote (summary view), linked to its full node,
 * and classed as "randomquote-link" for easy styling.
 */
function randomquote_link()
