Introduction
============

Description
-----------

Add sort options to the fetch( ezfind, search, ... ) template function.


Design
======

Sort options for fetch( ezfind, search, hash( ... ) ) are specified in the
hash parameter by 'sort_by'. The possible sort options are:
- relevance | score ( default )
- <class_name>/<attribute_name>[/<sub_structure>] | <class_attribute_id>[/<sub_structure>]
- modified
- published
- author
- class_name
- class_identifier
- name
- path
- section_id

Sort order are:
- asc
- desc

Examples: 
- fetch( ezfind, search, hash( 'query', 'eZ Publish',
                               'sort_by', array( 'modified', 'asc' ) ) )
- fetch( ezfind, search, hash( 'query', 'eZ Publish',
                               'sort_by', array( 'created', 'desc' ) ) )
- fetch( ezfind, search, hash( 'query', 'eZ Publish',
                               'sort_by', array( array( 'class_name', 'asc' ),
                                                 array( 'created', 'desc' ) ) ) )
- fetch( ezfind, search, hash( 'query', 'eZ Publish',
                               'sort_by', array( 'class_name', 'asc',
                                                 'created', 'desc' ) ) )

The implementation will be done by extending the functionality in 
ezfeZPSolrQueryBuilder.
