Fix source of crash during topology checks
flynnarray.cc:
FIxes to catch bad input to functions
general.cc:
Do proper type cast
init.c:
Initialise rand in case some processes still use it rather than the Elle
random
interface.cc:
Only use F_ style keywords for file input
nodes.h, nodesP.cc
Added a fn which fortran could call in basil2elle (polygonavg.f). This
fn still makes assumptions about the Elle unitcell dimensions and should
be generalised.
splitting.cc:
fix format of triangulation output to file
tripoly.c:
Match eps values
unodes.cc:
Lots of changes and fixes for voronoi of unodes to create enclosing
flynns
voronoi.h:
specifically copy Coords fields
