/*

  The CodeChunk class represents a tiny piece of C++ code.

  The class provides convertion between a list of lexemes and a string.  It adds

  spaces at the right place for consistent style.  The tiny pieces of code it

  represents are data types, enum values, and default parameter values.

  Apart from the piece of code itself, there are two bits of metainformation

  stored in CodeChunk: the base and the hotspot.  The base is the part of the

  piece that may be a hypertext link.  The base of

      QMap<QString, QString>

  is QMap.

  The hotspot is the place the variable name should be inserted in the case of a

  variable (or parameter) declaration.  The base of

      char * []

  is between '*' and '[]'.
