Defining SPARQL commands in Jena rules

[Miguel Bento Alves]

Hi all,

I updated my repo https://github.com/mbentoalves/jena. Now, it’s possible to 
combine sparql commands with rules terms in a rule. Example: 
 (?x rdf:type ex:IronMan) <-
    ex:ironMan ex:numberOfSports ?n .
    (\\\SPARQL  
         (Select ?x     
         Where {    
             ?x ex:playSport ?y .   
         }  
         group by ?x    
         having (count(1) >=&n)
     \\\SPARQL). 
This is working in all engine modes but I implemented a new engine to evaluate 
this kind of rules. Therefore, every time that a rule that combines sparql 
commands with rules terms needs to be evaluated, is called a specific engine 
for that. 

With this, I finished all implementation in this work. However, in next future 
I will try to improve the documentation with better illustrative examples.
