Import `textgrid`: Facilitate tier name listing by allowing regular expressions

[MartinKl]

Assume there is a tier morph with annotations morph-cat, morph-flex, etc, instead of configuring tier_groups this way:

morph = ["morph-cat", "morph-flex", ...]

one could allow for:

morph = ["morph-.*"]

This comes in handy when there are a lot of tiers with a fixed naming scheme and might also encourage users to think about there annotation names in a different way.]

I'm trying to use a toolbox importer but I do not understand what this setting means. Here, 'morph' and 'morph-cat' has both to be tier names, isn'it ? What is produced by their association in this formula?

[MartinKl]

Do you mean toolbox or textgrid? As this is an issue on enhancing the import of textgrid files, would you mind opening a new issue elaborating on your troubles a little more and on what you are trying to achieve? I'd be happy to help!

arg, textgrid, sorry. I'm not sure to understand what the 'morph = ["morph-cat", "morph-flex", ...]' formula stand for (what is "annotation" in the importer doc?). The importer complains (but doesn't crash) when either the left side or the right side of the assignation is not toolbox tier(s). I would be reinsured by being able to export back the textgrid from the salt graph with the textgrid exporter. Also it looks like the timestamps of the timeline are not imported. Sorry for this messy report. With better understand about the parameters of the importer I will try to narrow down the problem(s) -- if there are. Thank you very much for any help.

I opened #491, we can continue over there :)
