Remove obsolete LDFLAGS flags for Darwin.
Define LIBS to have .../conf/dep/lib.
Improve quick-start instructions.
For Darwin, twist LDFLAGS to get libfmtkUtils for sim1engine.
Only libfltSim1 needed to link to flightsim at build-time.
libfmtkSim1 is build to be dynamically loaded.
Put scenario name in sim.log
LDFLAGS should not default to -dynamiclib in Darwin.
Resolve Writer:: refs for flightsim by -lfmtkUtils.
Distinguish "traj" and "atmos" entries in data logging.
Allow scenario to control when to put data.
Expand SimpleFlight to more realistic scenario.
Falling body with data logging of trajectory and atmospheric conditions.
Add -lfmtkModels for Darwin.
Add optional logname to Writer.
More appropriate example for unpowered, airless flight.
Use scenario name as basis of writer logname.
Add module SimpleDrop.
Add 'drop1' target; factor out symlink to dynamic library.
Simplify paths starting './'; force build path to absolute.
In quickstart(), replace findpath...() by arg tkroot.
Discover tksrcdir and pass to quickstart().
