extractLocalFun
Extracts local function from
wrapper functions of the following type, typically used
in S4 methods: function(a, b, ...){ .local <-
function(a, b, c, d, ...){} .local(a, b, ...) }
Works for methods that are created (setMethod) as a wrapper function to an internal function named .local.
