Reworking API internals about phpsyllable

[vanderlee]

As for a PSR-6 implementation. I prefer https://packagist.org/packages/symfony/cache, basically because it's by far the most popular and I use Laravel in daily live, which heavily borrows from Symfony. Your thoughts?

I suggest starting a new 'refactor' branch for these and related changes. There are a number of thing I'd like to see improved as well, such as the parser, support for character substitution in the Tex files and namespaces. I'm also keen to trying to achieve 100% unittest coverage. I'd liked to support at least the latest 5.x PHP version, but otherwise don't mind restructuring everything. Do note that the hyphenation part of this library has been heavily performance profiled and optimized, so I'd rather not touch the actual algorithms. Considering the recent flurry of activity, now might be a good time for an overhaul. I'm currently spending most of my time doing a similar overhaul of another github project, but will have ample time to devote to this in a couple of weeks.

I've started a refactor branch with /src, namespace and a BC autoloader (based on your code, but changed somewhat for performance reasons). Feel free to take a look and experiment with it.
