// Step: The title that the student sees in overview/progress panel
// Type: specifies whether this is a recursive script or wizard
// Location: specifies where to find the script; Used by WizardFactory to determine the wizard to use
//     and by ScriptModel to find the appropriate script
// For Location Step: 
//     Section: The section in code in which the student must locate it
//     Action: The value of Statement in specification that points to what the student should have selected
//         e.g., could be Subsection, Prompt or Input for variable input
// Modifies: The name of the attribute modified in problemSpec which can be used by a subsequent step
//     to conditionally pick a course of action

// Steps:
//    - ask for control structure
//    - ask to identify the block to repeat
//    - Ask to write the shell
//    - Ask to write the correct condition
//    - Ask to negate the correct condition
//    - Optionally, have DeMorgan's Law wizard kick in to simplify the condition


// Identify whether expression, selection or repetition
Step: Identify the type of control statement for validation
Type: Wizard
Location: validation_control
Modifies: data.validation.control
// Note that this step sets data.validation.control attribute, which is used by next step

// Select the type of loop
Step: Select the loop type for validation
Type: Wizard
Location: $data.validation.control
Modifies: data.validation.loop
// Note that this step sets data.validation.loop attribute, which is used by next step

// Have the student write the loop
Step: Write the loop
Type: Script
Location: control/validate_$data.validation.loop
// Note that we are asking for the script specified from the previous step to be used
