remove CFC code

[agramfort]

here is a new package by @TomDLT on CFC

https://pactools.github.io/index.html

cc @choldgraf @SherazKhan

I am tempted to remove the CFC code from sandbox and tell people to use this package

any opinion?

Nice theme :)

[choldgraf]

I'm fine with this, is there anything in this module that could be contributed to the other package? @TomDLT what do you think? See the examples for current user-facing functionality
