Transform plotprofmle in S4 method?

[andrechalom]

Should we transform plotprofmle in an S4 method?

That would allow us to define a method for fitsad/fitrad that calculates the profile and draws the plot, instead of throwing back a "not a profile or profile.mle2 object" error.

I suggest the plotprofmle method applied on a fitsad/fitrad object should "cat" the following:
"NOTICE: calculating the profile for this fitted object. You should consider storing the profile in a new variable and calling plotprofmle on the resulting object."

I agree.
