/// The purpose for applying these default file ordering values is to ensure that common libraries such as jquery are always located
/// at or close to the top within a bundle. These values can be all removed with <see cref="ResetAll"/>.
///
/// The default ordering values are as follows:
/// <list type="bullet">
/// <item><description>reset.css</description></item>

/// <item><description>jquery.js</description></item>
