    \class Overview

    \brief The Overview class converts a FullySpecifiedType and/or any qualified
    name to its string representation.

    The public data members (except the ones starting with \e marked)
    determine what exactly and how to print.

    You can get the start and end position of a function argument
    in the resulting string. Set \c markedArgument to the desired
    argument. After processing, \c markedArgumentBegin and
    \c markedArgumentEnd will contain the positions.
*/

/*!
    \enum Overview::StarBindFlag

    The StarBindFlag enum describes how the '*' and '&' in pointers/references
    should be bound in the string representation.

    This also applies to rvalue references ('&&'), but not to pointers to
    functions or arrays, because it seems to be quite uncommon to use spaces in
    them. For example:
    \code
      void (*p)()
      void (*p)[]
    \endcode

    See the examples below. These assume that exactly one
    flag is set. That is, it may look different with
    flag combinations.

      \value BindToIdentifier
             e.g. "char *foo", but not "char * foo"
      \value BindToTypeName
             e.g. "char*", but not "char *"
      \value BindToLeftSpecifier
             e.g. "char * const* const", but not "char * const * const"
      \value BindToRightSpecifier
             e.g. "char *const", but not "char * const"
