plslabelfunc: Assign a function to use for generating custom axis labels
This function allows a user to provide their own function to provide
axis label text. The user function is given the numeric value for a
point on an axis and returns a string label to correspond with that
value. Custom axis labels can be enabled by passing appropriate
arguments to plenv, plbox, plbox3 and similar functions.
