Overview

A boolean “or” group. The implementation is to pass in 2 set of (repeaters of) groups. The simplest example is: /a|b/ If you have more than one boolean “or” operator, then this is initially parsed as an OrGroup containing another OrGroup. However, in order to avoid probability distribution issues in Regexp#random_example, this then gets simplified down to one OrGroup containing 3+ repeaters.
