Beginning of marc stuff :

Beginning of marc stuff :
* in marc directory, the marcschema.sql contains now the new marc structure. The old one is in marcschema.old.sql.
* in marc directory, the fill_usmarc.pl script fills the structure tables with USMARC format in english. Thanks to steve for the BIG work getting them from LOC... It's still to do for UNIMARC in english, and of course in french for me ;-)
* in admin directory, the marctagstructure.pl script helps playing with the structure and modifying it... It's not ended (tomorrow, i hope it will be)
