Plot (or return) surface interpolated from supplied vertices.

I often need to visualise a surface formed by a set of vertices when those vertices are not on a regular grid. surf() won't do this, so i made this file to generate the surface then plot it. The suffix `i' indicates "interpolate".

Also included is triangulate (a port from third party code, see help for details), which returns the surface without plotting it. This needs compiling before use.

Note that if you sort vertices before passing them to the function performance will generally be better, since you can sort them more intelligently than the algorithm can. See "help surfi".
