Bruno Schmitt fe6bb87e54 Merged alanmi/abc into default 2016-05-19 22:11:14 -03:00
Bruno Schmitt f93fbc2303 Fix the problem of not identifying divisors when its originating cubes had only 2 literals. 
With this change, 'empty' sub-cubes (sub-cubes with an ID equal to zero) are inserted  in the 0th bin of the hash table.
