PR proposal: anyGreater()

[rorynolan]

I like anyValue() and I'd like to add anyGreater(), anyLess(), anyGreaterOrEqual() etc plus all of the row and column variants. I often find myself doing any(x > 3) or something like that and these calculations are inefficient in base R because the whole of x > 3 gets calculated.
I can do this as a PR but I want to make sure you like the idea before going and doing it. If you like it, advice on how to name these functions would be appreciated.
