Performance improvements?

[ChrisCooney]

Hi all, had a read through the documentation and struggling to see any potential caching going on? As far as I understand it, Juice will go around reading in the contents of files and inlining them into the string. Could some caching be implemented in the app to prevent recurring reads of the same files?

If this isn't an option, are there any tips for performance tuning that you would recommend?

It might be helpful to understand how you are using the library and to see some logs that indicate that there are meaningful perf issues with file reads as opposed to somewhere else. For a perf related PR, I'd like to see before and after timing results.
