Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args, &block) ⇒ `Object`

# File 'lib/mo.rb', line 248

def method_missing(name, *args, &block)
  lookup_name = name.to_s
  return @attributes[lookup_name] if @attributes.key? lookup_name
  return set_prop(lookup_name.chomp('='), args[0]) if @attributes.key? lookup_name.chomp('=')
  child_matches = []
  @children.each do |child|
    child_matches.push(child) if child.class.prefix.sub('-', '') == lookup_name
  end
  return child_matches if child_matches.length > 0
