Examine adding end of block markers for Conditional Statements

[lynnlangit]

We've had several requests from users (teachers) to add English comment for 'end of block' statements for 'if' statements (as we do for end of methods and others)

We have decided to put more complete explanations in the written (teacher) documentation and NOT to add English comments in the recipes to indicate IF statement end locations.
