Enable Regular Expression Searches

Sometime back in 2014 an Accordance user by the name of Darin Franklin created an app called RegexForAccordance that allows MacOS users to search for Regular Expressions in English, Hebrew, and Greek texts in their Accordance library. This is a really brilliant app, but it would be nice if functionality like this was incorporate into Accordance natively so that Regular Expression searches could be run by both Windows and MacOS.
