Added *.txt to .gitignore, slight alteration to core prime test, and waffled around on 187.
Started problem_100.py
First attempt at 119.
First naive attempt at 122
Solved 179. Snipin' the easy ones.
Finally solved 77 (in 77nn.py). Still wouldn't mind finding the DP solution.
Solved 86 but not in sufficient time I dun't think.
First naive attempt at 88
Pretty sure I'm about ten thousand miles from solving 94
I like my stack implementation to handle backtracking in the sudoku solver, but it's bugging out at the moment.
