Poset: List (super)greedy linear extensions

[jm58660]

There is already greedy_linear_extensions_iterator and supergreedy_linear_extensions_iterator in hasse_diagram.py. Might be nice to have a wrapper function for them in the finite posets class.

Should these be 1) two new functions, 2) one new function, or 3) addition to current linear_extensions() function?

I'll CC Frédéric, as he might have ideas about this. The function can be just oneliner, so one possibility is to just forget this. However, it may be little hard for a beginner to use _hasse_diagram directly. OTOH a class for special subset of linear extensions seems unnecessary.

Created the wrapper function using the third method specified
