Returns an array of the requested Atoms from the Structure object.
Iterates over all groups and checks if the requested atoms are in this
group, no matter if this is a {@link AminoAcid} or {@link HetatomImpl}
group. If the group does not contain all requested atoms then no atoms
are added for that group. For structures with more than one model, only
model 0 will be used.

@param s
the structure to get the atoms from

@param atomNames
contains the atom names to be used.
@return an Atom[] array
