Molten output doesn't respect -b flag

[m-a-martin]

When outputting in molten format with the -b flag, output should only include unique combinations instead of outputting all combinations.

@m-a-martin -b Blank top left corner cell is about the output cell at (0,0) ?

ah, sorry, that's my mistake, not sure how I mixed that up. in general though, a feature to only output either the upper or lower triangle of the matrix or only calculate/output unique combinations in the molten output would be useful, especially on very large datasets.
