/**
* A Javascript implementation of the CSL citation formatting language.
*
* <p>A configured instance of the process is built in two stages,
* using {@link CSL.Core.Build} and {@link CSL.Core.Configure}.
* The former sets up hash-accessible locale data and imports the CSL format file
* to be applied to the citations,
* transforming it into a one-dimensional token list, and
* registering functions and parameters on each token as appropriate.
* The latter sets jump-point information
* on tokens that constitute potential branch
* points, in a single back-to-front scan of the token list.
* This
* yields a token list that can be executed front-to-back by
* body methods available on the
* {@link CSL.Engine} class.</p>
*
* <p>This top-level {@link CSL} object itself carries
* constants that are needed during processing.</p>
* @namespace A CSL citation formatter.
