Frame data caching about ratchet

[cboden]

Took a quick look at caching libraries that included a memory cache implementation. The short list:

• Stash
• Laravel
• illuminate
• Zend

I would like to suggest Doctrine's Cache-Component as many of ratchet's users may use Symfony because of the session-Integration and this will save one dependency: Doctrine

Doctrine did indeed have the best API. It's nicely decoupled.

I implemented it, did some testing and determined the hashing and looking was as process intensive as framing the message. I think caching would only be beneficial for clients as masking the message would be heavy.
