Concatenates a vector. As with PrintVector(), the vector will be concatenated in this form:
<x.000000 y.000000 z.000000>. Syntax:
jkStringConcatVector(vector);
vector: Remember that Cog treats all three-numbered variables the same. You may
concat positions, RGB values, velocities, or any value in vector form with this verb. You can also give the vector in
'x y z' form.
