Usage:
1. dolfin-plot <meshfile>
where <meshfile> is a mesh stored in DOLFIN XML format
with suffix .xml or .xml.gz.
2. dolfin-plot <family> <domain> [degree] [rotate=1/0]
where <family> is the name of a finite element family,
<domain> is the domain type ('triangle' or 'tetrahedron'),
and <degree> is an optional degree for elements that
support variable degree.
Examples:
dolfin-plot mesh.xml
dolfin-plot Lagrange triangle 3
dolfin-plot BDM tetrahedron 5
dolfin-plot Hermite triangle
List of supported element families:
%s
A (*) indicates that the element is not supported by DOLFIN/FFC,
but the element may still be plotted.
