# Identifies Ext JS builtins like Ext.define and Ext.extend, taking
# also into account the possibility of aliasing the Ext namespace.
#
# For example when the following command line option is used:
#
# --ext-namespaces=Ext,MyApp
#
# we need to identify both Ext.define and MyApp.define, but
# Ext.define is additionally aliased withing ExtJS as
# Ext.ClassManager.create, so we also need to recognize
# Ext.ClassManager.create and MyApp.ClassManager.create.
#
# The matches? method will take care of identifying all these four
# cases:
#
# ps = ExtPatterns.new(["Ext", "MyApp"])
# matches?("Ext.define", "MyApp.define") --> true
#
