[librecat-dev] fix that can removes all fields except some set of desired fields

[Jonathan NORRIS]

Hello,

I could not find anything in the fixes documentation for this and I am 
wondering if it exists.

I want to create a yaml export with only the _id, title, and DOI of a 
record. Is there any fix functions that allow you to do this in any 
other way that just calling remove_field() on all the undesired fields? 
Like, is there a way to generate the format from specifically chosen 
fields? Or is it always based on removing fields from the full record?

To illustrate better:

-------
# generates the export from specifically chosen fields
add_field(_id)
add_field(title)
add_field(doi)
-------

-------
# remove all unwanted fields
remove_field(a)
remove_field(b)
remove_field(c)
remove_field(d)
remove_field(e)
remove_field(f)
etc..
etc..
etc..
-------


Thanks for any help!
