A string pattern.

A Pattern<'a> expresses that the implementing type can be used as a string pattern for searching in a &'a str.

For example, both 'a' and "aa" are patterns that would match at index 1 in the string "baaaab".

The trait itself acts as a builder for an associated Searcher type, which does the actual work of finding occurrences of the pattern in a string.
