//! This class implements the real IntegerVector abstract data type.
//! IntegerVectors can have an arbitrary range which must be define at
//! the declaration and cannot be changed after this declaration.
//! Example:
//! @code
//! math_IntegerVector V1(-3, 5); // an IntegerVector with range [-3..5]
//! @endcode
//!
//! IntegerVector is copied through assignement :
//! @code
//! math_IntegerVector V2( 1, 9);
//! ....
//! V2 = V1;
//! V1(1) = 2.0; // the IntegerVector V2 will not be modified.
//! @endcode
//!
//! The Exception RangeError is raised when trying to access outside
//! the range of an IntegerVector :
//! @code
//! V1(11) = 0 // --> will raise RangeError;
//! @endcode
//!
//! The Exception DimensionError is raised when the dimensions of two
//! IntegerVectors are not compatible :
//! @code
//! math_IntegerVector V3(1, 2);
//! V3 = V1; // --> will raise DimensionError;
//! V1.Add(V3) // --> will raise DimensionError;
//! @endcode
