add
Create and add a bootstrap A_Styler in the method specified by the atom. If the method already has a styler, do nothing. Also do nothing if the bodyCode is not primitive, or its primitive doesn't specify a bootstrapStyler.
DO NOT record this action, as it will happen as an automatic consequence of adding the method definition or macro during fast-loading.
Parameters
body
The body of the method definition, macro, or lexer that was defined. If it's a primitive, its bootstrapStyler will be looked up.
atom
The A_Atom whose bundle's method that should have a styler added, if indicated.
