Cacheing output of expensive function calls

[tc1]

Hey @fonnesbeck and @andrewPoulton ,

Might have already seen the updated docs, but if not [or if anyone else comes across this thread] wanted to give you all a quick update that the documentation @Jonathan_Rhone was mentioning was released this month. Here are some helpful links:

• Improved caching docs
• New docs on advanced caching and hash_funcs
• New cache troubleshooting docs

If you come across any issues or would like more context, here is a helpful topic.
