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. 




@ruiting and @linas should degree(much, comparative) be degree(more, comparative) as it is a attribute of the word more? And similarly with degree(little, comparative) be degree(less, comparative) ?
