Define a category toolbox

A category toolbox has multiple sets of blocks that are arranged into different categories.

A category toolbox with Control and Logic categories. The Logic category is open and the flyout toolbox contains comparison, and-or, and true-false blocks.

To create a category toolbox, pass JSON or XML describing the toolbox to the toolbox property of the configuration options.
