Define "glob"

[jyutzler]

In the schema section we use the term "glob" but it is never defined. Defining this term would help the reader understand what the intent is.

Maybe just link to https://www.sqlite.org/lang_expr.html#glob

More generally, constraints might benefit from an informative annex, or perhaps this could be in some separate "advanced geopackage" example-heavy tutorial.

In today's SWG we agreed that referencing the SQLite page was sufficient.

This issue will be closed once the proper pull request is applied.
