add mesh and blockage info to .smv file

[gforney]

you can add mesh connectivity info to the GRID keyword. This is what is output now - smokeview doesn't use the trailing 0

GRID
ibar jbar kbar 0

just add 6 mesh face connectivity integers to the right of ibar jbar kbar (getting rid of the 0)

GRID
ibar jbar kbar left right front back down up

I had originally said to let the left/right/.../up parameters be 0 if mesh side is completely connected to the outside, 1 if completely connected to the inside or 2 if connected to more than one mesh or the outside

does fds know what mesh a mesh side is connected to. if so smokeview could use that info. maybe change integers to
i = 0 - mesh side completely connected to outside (as before)
1<= i <= nmeshes - mesh side completely connected to mesh i
i=-1 mesh side connected to one or more meshes or the outside

this is for blockage info

fds now outputs whether a blockage is removable using
WRITE(MYSTR,'(8I5,A,L1)') OB%I1,OB%I2,OB%J1,OB%J2,OB%K1,OB%K2,OB%COLOR_INDICATOR,OB%TYPE_INDICATOR, &
' ! ',OB%REMOVABLE; CALL ADDSTR

when it dumps 'OBST' info (near line 2225 in dump.f90)

I suggest adding 6 more integers after OB%REMOVABLE
indicating whether left, right, front, back, down, up, blockage faces
are not visible ie completely hidden by other blockages (0)
or are visible (1)

I added the 6 integers to the end of the OBST lines in the .smv file. Give it a try. If it works, we can then do it for MESHes.

thanks. I'm working on implementing the smokeview side
