We can add new function strstrtrev("piece", "/") that would return the last 
occurence of the substring.

Would it be useful to have function for handling file names
	strfileparts('/home/me/bla.dat',n)
which would return path (for n=1), name (n=2) and extension (n=3)?
That would be quite handy especially in the "plot for" loop.

I have added it.
