def flash
  Current.session.flash
end

- (Object) flashbox(tag = ancestral_trait[:flashbox])

Use in your template to display all flash messages that may be stored. For example, given you stored:

flash # => { :error => 'Please enter your name' :info => 'Do you see the fnords?' }

Then a flashbox would display:

Please enter your name
Do you see the fnords?

This is designed to be customized permanently or per usage:

flashbox("

%value
")

Where any occurrence of %key and %value will be replaced by the actual contents of each element of flash
