Description of problem:
Functions saved in *.function files are not correctly migrated. The header "function <filename>" is prepended and word "end" appended to migrated files. For example:

    function String getStringFunction(String arg) {
        return "some string";
    }

gets migrated to:

    function 'Function'

    function String getStringFunction(String arg) {
       return "some string";
    }

    end

Same migration steps as for DRL are used which is wrong. Functions should be migrated as is, without any words prepending/appending.
