Description: Query a daterange on objects with a daterange.
        
        Example: You want all events within a date range of next two weeks, neither if 
        the event has started one week ago nor ends one week later - or both.
        
        Consider objects with a daterange start and end. 
        Use this addon to query all obejcts inside a query-start and query-end range, 
        where either or both of objects start and end match the query range.
        
        This index is possibly the fastest way to solve the problem, it solves it as an 
        zope index and works direct with the catalogs fast IISets (or IFSets). Its much 
        faster than formerly used classical catalog-query post-processing.
        
        There are two types of indexes available: 
        
        - ``Products.ZCatalog`` (Zope 2) compatible
        
        - ``zope.catalog`` (Zope (3) framework) compatible
        
        The index acts as an proxy for a more complex query on two indexes (DateIndex 
        on ZCatalog or FieldIndex on zope.catalog). It utilize the other indexes and 
        does not store any index-data itself.
        
        To illustrate this a query example on ZCatalog)::
        
            >>> result = zcatalog.search({'myindex': {'start':'2000-10-01 00:00',
            ...                                       'end':'2010-10-31 23:59'} })
        
        or a query example on zope.catalog::
        
            >>> query = catalog.apply({'myindex': (datetime(2000, 10, 01, 00, 00'), 
            ...                                    datetime(2010, 10, 31, 23, 59'))})
        
        This will find objects (consider start is always before end date): 
        
        1) where start date is before 2000-10-01 and end date is after 2010-10-31.
        2) where start date is between 2000-10-01 and 2010-10-31.
        3) where end date is between 2000-10-01 and 2010-10-31.
        4) where both are between 2000-10-01 and 2010-10-31.
        
        ASCII-Art of the above (q=query, e=event)::
                    
             Q)    q_start|--------------------|q_end
             
             1) e_start|---------------------------|e_end
            
             2) e_start|---------------|e_end
             
             3)           e_start|-----------------|e_end
            
             4)           e_start|-----|e_end

        ===========
        
        The sources are in a GIT DVCS with its main branches at 
        `github <http://github.com/collective/Products.DateRangeInRangeIndex>`_.
        
        We'd be happy to see many commits, forks and pull-requests to make 
        DateRangeInRangeIndex even better.
