has been slightly modified (see ending of point 5).
a) The phrase "dynamic stability" has been replaced by "stability."
b) The incorrect sentence was removed.
c) Numerical illustrations were added to justify 3-dimensional
stability if the orbit.
I wish I could justify the 3-dim stability in a more convincing way,
for this 3-body system. Any help would be appreciated.
