Add new unit test sentences 

I have added test sentences of sub-category, Non-equal Gradable :Two entities one feature with more/less, 
from the discussion google doc https://docs.google.com/document/d/1tsBhFp-lvPfh4CvtiJYzjAeKuzNKYNxA7DXbqXRuvJA/edit
By work on the all the sentences in a subcategory at once, I would be able to check how the changes that I'm making for one sentences is affecting the others.
@linas , @AmeBel, @rodsol , @ruiting please review the new test sentences added. 




the google doc(https://docs.google.com/document/d/1tsBhFp-lvPfh4CvtiJYzjAeKuzNKYNxA7DXbqXRuvJA/edit) mention this as "degree(more, comparative)" but I guess it should be as above?
