Convex - summary of changes

1.0
===
first "official" release

1.0.1
=====
CFACE[preimage]
bugfix: only accepted type 'mat' as second argument

FAN[isquasipolytopal]
bugfix: didn't test whether there were any strictly convex support functions
at all (observed by Marcel Widmann)

PCOMPLEX[hplanes]
bugfix: signs were on the wrong side

1.0.2
=====
POLYHEDRON[faces], PFACE[succ]
bugfix: needed POLYHEDRON[edges], which was removed in 1.0 (observed
by Thorsten Theobald). Now defined CONE[_edges] = POLYHEDRON[_edges] in
cone_polyhedron.mt with synomym CONE[edges] in cone.mt, and changed
all references of POLYHEDRON[edges] to POLYHEDRON[_edges]
