Depend on centralized standard

[XedinUnknown]

Hi,

I know that FIG hasn't published their PSR-14 interfaces separately, and this is a problem that I came across when making my implementation. However, I have taken care of publishing them separately until FIG does that. This could make your implementation much more interoperable, and therefore usable in cross-platform modules. I suggest you take a look at dhii/psr-14. If you decide to go for it, I suggest you depend on ^0.1, since 0.1.x is guaranteed to maintain BC with the current state of the PSR-14 spec.
