Added support for drawing curves and arcs with an example. This was adapted

from the geometric figures FPDF script by David Hernández Sanz, with a starter
function provided by Anthony Starks.

Anthony Starks also made a case for not closing the io.Writer after it is used
to produce a document. An additional method, OutputAndClose, was added so that
the library can close the writer if desired.
