Thanks @carlos8f for a greatly prepared pull reuest. I will merge it with the source

@Starcounter-Jack can you remind what was the reason for ~1, ~0 stuff in first place? Those were some special triggers, I suppose? Maybe it just can be removed now.

[carlos8f]

@warpech ~0 and ~1 are the escaped (literal) versions of ~ and /, respectively, according to the JSON pointer spec.

Ah, I oversaw it... So apply takes escaping in consideration (though fails on multiple escaped characters), while generate does not consider them at all

[carlos8f]

correct :)

Thanks, I included your fix in v0.3.3
