Starlib: formatNMRSTAR

There is a routine in starlib that will format NMRSTAR files by setting appropriate comments and by spacing the residue sequence codes with multiple iterations per text line. You call this routine just before doing an Unparse().

This routine has already been incorporated into a simple program that can be called externally, so there are two ways now that you can use this code:

- As a standalone program:
The program is called 'formatNMRSTAR'. it is in the /bmrb/bin/ directory. It works as a simple 'filter', meaning it operates on standard input and standard output so you need to use redirection like so:
```
		    formatNMRSTAR < inputfile > outputfile.
		
```
This program uses the file /bmrb/lib/comment.str as a configuration file that describes the comments to be added. This file can be changed to add more comments later.
- The routine can also be used by a program in the following fashion:
1. - parse the input StarFileNode into memory.
2. - parse /bmrb/lib/comment.str into memory as a StarFileNode also.
3. - call this routine:
```
		        formatNMRSTAR( StarFileNode to be formatted,
			               StarFileNode holding the comment.str file );
		    
```
4. - call Unparse(..) to print it out.
These steps are demonstrated as an example in the file examples/formatNMRSTAR.cc, which is in the starlib CVS project.
