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. 




@AmeBel  I just checked the latest version of the relex rules. The _quantity_mod isn't outdated. I think we discussed about it to change _quantity_mod to _num_mod for the numbers, for the same reason that we added "_num_quantity" for numeric quantifiers. But I'm not sure if it's necessary for the modifiers, as the _num_quantity has already tagged the number sign. So I think we should change "_num_mod(ten, almost)" to "_quantity_mod(ten, almost)" here.
