Non-strict record grouping

[goodmami]

I had been working under the assumption that once a record marker is found (e.g. \\id or \\ref), any following lines until the next record marker are grouped with under that level. This is not always the case. The Toolbox project files define, for each marker, what is the level "above" it. So, for instance, it's possible to have a file like this:

\id my_text
\ref my_text.001
\t ...
\m ...
\g ...
\f ...
\ELANMediaURL ...
\dt ...
\id another_text
...

...where \ELANMediaURL and \dt are attributes of the \id my_text level.
