pdb2ac.tcl: Create DYNAMO atomic coord (AC) restraint table from PDB.

Flag	Argument	Default	Description
`-in`	`pdbName`	`ref.pdb`	PDB Input for Coords.
`-ref`	`seqName`	`None`	PDB Input for Sequence (If Different).
`-r1`	`r1`	`First`	First Residue for Sequence PDB.
`-rN`	`rN`	`Last`	Last Residue for Sequence PDB.
`-a1`	`a1`	`r1`	First Residue for Coord PDB.
`-id`	`id`	`1`	First Index Number for Restraint Output.
`-seg`	`segName`	`PROT`	Segment Name for Restraint Output.
`-dLo`	`dLo`	`0.0`	Lower Distance Bound.
`-dHi`	`dHi`	`0.0`	Upper Distance Bound.
`-fc`	`fc`	`10.0`	Restraint Force Constant.
`-atom`	`aList`	`C* ...`	Atom Name List. Default: C* N* O* S* P* F*
`-dx`	`dx`	`0.0`	Additional X-Axis Offset.
`-dy`	`dy`	`0.0`	Additional X-Axis Offset.
`-dz`	`dz`	`0.0`	Additional X-Axis Offset.
`-hetatm`			Include HETATM entries from PDB Input.
`-nohetatm`			Ignore HETATM entries (Default).
`-center`			Center Coords of PDB Input.
`-nocenter`			No Centering of PDB Input (Default).
`-hdr`			Print Header in Output (Default).
`-nohdr`			No Header in Output.
`-na`			Interpret Sequence for DNA/RNA. Also -dna -rna
`-nona`			No Adjustment for DNA/RNA (Default).

Coordinate Modes (Use Only One):

`-fixed`			Fragment Coords are Fixed (Default).
`-nofixed`			Fragment Can Translate and Rotate.
`-rotfixed`			Fragment Can Translate Only.

Multiple Fragment Mode (Zero for Single Fragment Mode):

`-segLength`	`sLength`	`0`	Segment Length of Fragments.
`-segStep`	`sStep`	`0`	Offset Between Fragments.
`-equiv`			Include All Tensor-Equivalent Rotations.
`-excl`	`resList`	`None`	Starting Res IDs Not to Rotate.

Notes:
Multiple Fragment Mode Uses '-nofixed' Coordinate Mode by Default.
