Subject: Tidy Comment

Remove self.
Use each rather than for
Use {} block rather than do/end
Use self. rather than ClassName. for class method
Indent private as much as method definitions
Remove explicit return
Line Length
Use inline if
Move callback before method definitions
Use unless instead of if !
