 * GeocellQuery splits the traditional query in 3 parts:
 * the base query string,
 * the declared parameters
 * and the list of object parameters.
 *
 * Additional information on http://code.google.com/appengine/docs/java/datastore/queriesandindexes.html
 *
 * This allows us to create new queries and adding conditions/filters like in the proximity fetch.
