This library is created for compile-once patterns. This means, that compilation could take time, but
strings matching is done faster, than in case when always parsing template.
If you will not use compiled glob.Glob
object, and do g := glob.MustCompile(pattern); g.Match(...)
every time, then your code will be much more slower.

Syntax is inspired by standard wildcards,
except that **
is aka super-asterisk, that do not sensitive for separators.
