Contains the registered collection processors available 'out of the box' with Spring
Expression Language. They are:<ul>
<li>sort() - sorts a collection
<li>nonnull() - returns a new collection containing the non-null elements from the input collection
<li>count() - returns the number of elements in the collection
<li>min() - returns the minimum element from the input collection
<li>max() - returns the maximum element from the input collection
<li>distinct() - returns a new collection where duplicates from the input collection have been removed
