This node is to create a checkbox on UI.MultipleInputForm++ forms.
InputName: This input lets you label the checkbox on the form. All it takes is a string.
DefaultValue: Lets you set the default value of the checkbox when the form first appears to the user. I takes a boolean input.
Side Text: Sets the text that appears next to the checkbox. The default text is "Yes/No". It is handy when you want to give more information to the user about the actions to come. This input takes strings.
The user input will be returned by UI.MultipleInputForm++ as a boolean value.
