Module group

Creates a group pattern in many different ways as desired.

This module consists of methods needed to create a group in many different ways, having different options/settings. The main one is the group method which takes an expression as argument and a set of meta as GroupSettings creates a group for it. Other methods starting with the into word followed by an underline makes all previously chained expressions into a group. They mostly take no arguments for settings and are useful to be added to the latter part of a method chain.
