Class
    Foam::dictionaryEntry
 
Description
    A keyword and a list of tokens is a 'dictionaryEntry'.
 
    An dictionaryEntry can be read, written and printed, and the types and
    values of its tokens analysed.  A dictionaryEntry is a high-level building
    block for data description.  It is a front-end for the token parser.
    A list of entries can be used as a set of keyword syntax elements,
    for example.
