AstSearchVisitor<T> mixin

A visitor that recursively traverses each statement and expression in a Sass AST whose visit* methods default to returning null, but which returns the first non-null value returned by any method.

This extends StatementSearchVisitor to traverse each expression in addition to each statement, as well as each selector for ASTs where parseSelectors: true was passed to Stylesheet.parse. It supports the same additional methods as RecursiveAstVisitor.
