Shows how to apply custom list formatting to paragraphs when using DocumentBuilder.

// A list allows us to organize and decorate sets of paragraphs with prefix symbols and indents.
// We can create nested lists by increasing the indent level.
// We can begin and end a list by using a document builder's "ListFormat" property.
// Each paragraph that we add between a list's start and the end will become an item in the list.
// Create a list from a Microsoft Word template, and customize the first two of its list levels.
