/** Holds a one-dimensional array of DAP2 data types.  This class
    takes two forms, depending on whether the elements of the vector
    are themselves simple or compound objects. This class contains
    common functionality for the List and Array classes, and should
    rarely be used directly.

    When each element of the class is a simple data type, the Vector
    is implemented as a simple array of C types, rather than as an
    array of BaseType data types.  A single private ``template''
    BaseType instance (<tt>_var</tt>) is used to hold information in common
    to all the members of the array.  The template is also used as a
    container to pass values back and forth to an application
    program, as in <tt>var()</tt>.

    If the elements of the vector are themselves compound data
    types, the array is stored as a vector of BaseType pointers (see
    the libdap class <b>BaseTypePtrVec</b>). The template is still used to
    hold information in common to all the members of the array, but
    is not used to pass information to and from the application
    program.

    @brief Holds a one-dimensional collection of DAP2 data types.
