Files/Grab info from PubMed for eprint

From EPrints

We use it by having a custom html page (not in the eprints pages) that submits directly to a slightly modified eprint creation/submission page perl_lib/EPrints/SubmissionForm.pm:

Here's the code for the html form:

<form action="http://eprintserver/perl/users/submit" method="GET">
   <input type="TEXT" name="pubmedid" size=10></input>
   <input type="hidden" name="_action_new" value="1"/>
   <BUTTON name="submit" value="submit" type="submit">Submit</BUTTON>
</form>

and in the perl_lib/EPrints/SubmissionForm.pm, after the new eprint has been created (around line 426), I inserted:

# import from PubMedID here
$self->{pubmedid}=$self->{session}->param( "pubmedid" );
if($self->{pubmedid}) {
   EPrints::Utils::import_pubmed($self->{eprint}, $self->{pubmedid});
   $self->{eprint}->commit();
}

Note that the import_pubmed code was originally missing some helper functions. This has been fixed.
