/* Write circle packing p to an open file fp. Return 0 on error.
If basic combinatoric data is to be included, use key "NODECOUNT:";
if only ancilliary data is to be included, use "CHECKCOUNT:".
(Note: specialized routines may be necessary: eg., when aims are
specified, only the non-default ones are included.)
When 'apend' is set, just add specified data (without NODECOUNT
or CHECKCOUNT) to existing file before 'END' (assume file is
open in "r+" read/write mode, positioned already, and will be closed
by the calling routine; don't allow 0001 bit to be set in act).
Data to write specified in 'act' with bit-code as follows:
basic combinatoric info:
1: 00001 nodecount, a/b/c, flowers, packname
(else (if not append), CHECKCOUNT: nodecount)
default standard:
2: 00002 geometry
3: 00004 non-default inv_dist & aims
4: 00010 radii
optional:
5: 00020 centers
6: 00040 angle sums
7: 00100 vertex_map (if it exists)
8: 00200 lists of verts/faces/edges (non default)
9: 00400 colors (non default)
10: 01000 nonzero vertex plot_flags
11: 02000 edge-pairing Mobius transformations
Note: standard write would be act= 0017, max would be act=0777.
