Hello World

<#
.SYNOPSIS
    Hello World Example - AdPowerForm
.DESCRIPTION
    Supports all the features of original HelloWorld (if nessesary):
    Passes in a parameter that contains a text string. If no value is passed
    in then prompt for text. If Value is "Hello" print "Good"
    else print "Bad". Keep prompting until a value is entered.
    
    A few extra ATPowerForm line: 
    Web page prompts for text string. If Value is "Hello" a new readonly
    textbox is dynamically added displaying "Good" else it displays "Bad". If
    empty is entered then the readonly textbox is dynalically removed. All
    done using events.
