Dihedrals
Where CA is the alpha carbon, C(-1) is the C before the current carbon, etc.

Now we want to add other stuff.

Cool. But do we always need to calculate stuff from the inputs? Not for the so-called "improper dihedrals", such as the C-CA-N-NH dihedral, or the C-CA-N-NH dihedral, because these are always the same. The "proper" dihedrals (N, CA, C) must be calculated from inputs, but the "improper" dihedrals can be taken from a table.

Build order
N terminus to C terminus, with increasing i
 * Within the residue, calculate proper dihedrals, take improper dihedrals from a table
