0030  * \class VectorCommand
0031  * 
0032  * \brief Implements the \"vector\" command.
0033  * 
0034  * VectorCommand constructs a vector by two ways:
0035  * 
0036  * The first way creates a vector from a list, with the same list elements.
0037  * \code vector(range(5)) \endcode 
0038  * constructs 
0039  * \code vector { 1, 2, 3, 4, 5 } \endcode
0040  * 
0041  * The second way creates a vector of size \"n\" filled with a value \"a\":
0042  * \code vector(n, a) \endcode
0043  * constructs 
0044  * \code vector { a, a, ... , a } \endcode
0045  *
