/**
* @class vtkSimpleBondPerceiver
* @brief Create a simple guess of a molecule's
* topology
*
*
*
* vtkSimpleBondPerceiver performs a simple check of all interatomic distances
* and adds a single bond between atoms that are reasonably close. If the
* interatomic distance is less than the sum of the two atom's covalent radii
* plus a tolerance, a single bond is added.
*
*
* @warning
* This algorithm does not consider valences, hybridization, aromaticity, or
* anything other than atomic separations. It will not produce anything other
* than single bonds.
