Inserts an atom of type <name> at the position <x,y,z> in crystal space. The temperature coefficient must be given. 'kick' checks the position <x>,<y>,<z> with respect to all atoms numbered <na> to <ne>. All atoms that are within the block <x> +- <delx>; <y> +- <dely>; <z> +- <delz> are removed from the structure.
If <dely> and/or <delz> are not given, then they default to the value of the last <del.> given on this 'kick' command.
Note that the <del.> are in fractional coordinates, NOT in Angstroem.
In the alternative form, the eight's parameter is interpreted as a bond distance. To distinguish the two forms, the bondlength must be less than zero. The new atom is inserted and all atoms within <bondlength> Angstroem from the position <x>,<y>,<z> are removed.
