Does a CFC exist?

Wow! Allen @ Prismix just stumped me in a big way. He asked if there was a function to see if a CFC existed. Somthing like isValidCFC(farcry.farcry_core.packages.farcry.rss)

there wasn’t but it was such a cool question, that I wanted to see if it was possible. The answer is yes and here is the code to do it.
