New description:
This patch introduces the following functions:
{{{
CanonicalFano SmoothFano
ReflexiveFano TerminalFano
PolytopeSmallPolygon lReflexive
LDP
}}}
These read from the data stored in this
spkg:[http://coates.ma.ic.ac.uk/GRDB_polytopes-20120806.spkg]
by using the new private function `_GRDBBlockReader` to access
classifications of the above Fano polytopes originally stored on the
[http://grdb.lboro.ac.uk Graded Ring Database] and return
`LatticePolytope` instances.
The implementation is similar that of
[http://trac.sagemath.org/sage_trac/ticket/13115 #13115] where we provide
a module `lattice_polytopes` to act as a namespace for these functions
which are situated elsewhere, giving the option to concentrate all future
examples of lattice polytopes here.
Install the latest SPKG above and the latest patch below.
