CSPICE_VSEPG returns the scalar double precision
separation angle in radians between two double precision,
N-vectors. This angle is defined as zero if either vector
is the zero vector.
For important details concerning this module's function, please refer to
the CSPICE routine vsepg_c.
Given two arbitrary N-vectors vec1 and vec2, calculate
the angular separation, return a value in radians:
separation = cspice_vsepg( vec1, vec2 )
