8FUNCTIONS: dnamlib - CYANA function

Synopsis: dnamlib(<integer>) = <string>

Character function that returns the name of torsion angle with index
<integer>, as it was originally defined in the residue library. In
contrast to the function 'dnam', possible renaming with the 'library
rename' command is not considered.

Optionally, the <integer> torsion angle index can be replaced by a
string consisting of the angle name and the residue number, separated
by a blank or a period, '.'.
