A bug in the evacuation geometry about fds

[gforney]

The problem was the 'sawtooth=.false.' default for the evacuation OBSTs.
Sawtooth=.false. does not work for obstacles that are only one grid cell thick. The
FDS5 fire calculation has the same problem, i.e., flow will go thorugh wall, if they
are defined as 'sawtooth=.false.' and are one grid cell thick.

The evacuation geometry has 'sawtooth=.true.' now, so there is no
problems with 'sawtooth=.false.'. And Kevin also corrected the sawtooth
feature, so one could also have 'sawtooth=.false.' for evacuation
geometry, but this is not needed. The evacuation flow fields seem
to be fine even with the 'sawtooth=.true.' case. So, let's say that
this issue is 'verified'.
