107 pass data through metamorph else

[dr0i]

See #107.

This is not exactly what @blackwinter proposed , but it enables the _else data to be passed through the input data as known (I would say "expected"), i.e. entity events are now also passed to downstream receivers.

A note: _else and the new _elseAndPassEntityEvents are not documented yet (TODO).

Example:

Input:

<mx:collection>
<mx:record xmlns:mx="http://www.loc.gov/MARC21/slim" id="ID1635091">
        <mx:datafield ind1="1" ind2="2" tag="123">
            <mx:subfield code="n">123</mx:subfield>
        </mx:datafield>
        <mx:datafield ind1=" " ind2=" " tag="456">
            <mx:subfield code="n">456</mx:subfield>
        </mx:datafield>
</mx:record>
</mx:collection>

morph:

<rules>
  <entity name="07812" >
    <data source="12312.n" name="new" />
  </entity>
  <data source="_elseAndPassEntityEvents" />
</rules>

output:

<marc:collection>
<marc:record>
    <marc:controlfield tag="type"></marc:controlfield>
    <marc:datafield tag="078" ind1="1" ind2="2">
        <marc:subfield code="new">123</marc:subfield>
     </marc:datafield>
     <marc:datafield tag="456" ind1=" " ind2=" ">
         <marc:subfield code="n">456</marc:subfield>
     </marc:datafield>
</marc:record>
</marc:collection>

Overall 👍, just a few minor (?) details that could be changed.

[dr0i]

I think everything is good know. What do you think?

[blackwinter]

Agreed, all conversations are resolved :)
