#3904 dispsym is not defined in manual

[Richard Gobeli]

dispsym occurs once in manual as an example, but is not defined or indexed in the manual.

(%i10) decsym(a,3,0,[cyc(all)],[]);

(%i12) dispsym(a,3,0);
(%o12)                     [[cyc, [[1, 2, 3]], []]]

It took me awhile to find how I could display the symmetry that I declared with decsym.
It would be nice to have this defined and then indexed in the available functions for itensor package.

Can this by added to the manual in itensor.texi?

This is an updated patch which adds the function dispsym to the itensor.texi file. It would be nice if someone could add this to the master.
Thanks,

I think this is done after the link to the example in decsym is fixed. The reference to decsym should be the following @mref{decsym} as in canform.
