    Placed inside a function, this will insert an IPython interpreter at that
    current location.  This will enabled detailed inspection of the current
    execution environment, as well as (optional) modification of that environment.
    *num_up* refers to how many frames of the stack get stripped off, and
    defaults to 1 so that this function itself is stripped off.
