    Hi 
    
    Please find updates on the PR.
    
    **Capturing output**
    
    This change is complete. Added class ResponseOutputStream to capture the 
result while written on OutputStream 
    
    **Caching and content negotiation**
    
    The Cache Key now contain ResponseType ContentType.
    
    **Cache invalidation**
    
    The SPARQL_Update servlet now invalidates the cache.
    
    **Configuration and Control**
    
    The SPARQL_Query_Cache now catches the requests and only passes the request 
to SPARQL_Query in case of cache miss.
    
    **Reuse the Guava already in Jena**
    
    Complete. I have cleaned up the CacheStore, CacheClient CacheGuavaClient 
implementation classes as well. Only CacheAction and CacheEntry classes are 
present to control cache operations and to wrap the result sets.
    
    **Documentation and tests**
    
    I am currently working on the units tests and documentation.

> Add a caching layer to Fuseki to cache the results of SPARQL Query requests.  
> This cache should allow for in-memory and disk-based caching, configuration 
> and cache management, and coordination with data modification.
