addMemoization

Creates a copy of an existing function such that its results are memoized

Creates a copy of an existing function such that its results are memoized.

## Default S3 method:
addMemoization(fcn, envir=parent.frame(), ...)

`fcn`	A `function` (or the name of a function) that should be copied and have memoization added.
`envir`	The `environment` from where to look for the function.
`...`	Additional arguments for controlling the memoization, i.e. all arguments of `memoizedCall`() that are not passed to `do.call`().

The new function is setup such that the the memoized call is done in the environment of the caller (the parent frame of the function).

If the function returns NULL, that particular function call is not memoized.

Returns a function.
