0024547: Convertation of the generic classes to the non-generic (math).

Browse Source 
- class "math_DoubleTab" was converted to the non-generic class. Some changes were made in the class "math_Matrix". And some stylish changes were made.

- class "math_SingleTab" was converted to the non-generic template class. And classes "math_Vector" and "math_IntegerVector" converted to the non-cdl, because they use template class "math_Vector". Some stylish changes were made.

class IntegerVector from math
---Purpose:
-- 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: math_IntegerVector V1(-3, 5); // an IntegerVector with
-- range [-3..5]
--
-- IntegerVector is copied through assignement :
-- math_IntegerVector V2( 1, 9);
-- ....
-- V2 = V1;
-- V1(1) = 2.0; // the IntegerVector V2 will not be modified.
--
-- The Exception RangeError is raised when trying to access outside
-- the range of an IntegerVector :
-- V1(11) = 0 // --> will raise RangeError;
--
-- The Exception DimensionError is raised when the dimensions of two
-- IntegerVectors are not compatible :
-- math_IntegerVector V3(1, 2);
-- V3 = V1; // --> will raise DimensionError;
-- V1.Add(V3) // --> will raise DimensionError;

class Vector from math
---Purpose:
-- This class implements the real vector abstract data type.
-- Vectors can have an arbitrary range which must be defined at
-- the declaration and cannot be changed after this declaration.
-- math_Vector V1(-3, 5); // a vector with range [-3..5]
--
-- Vector are copied through assignement :
-- math_Vector V2( 1, 9);
-- ....
-- V2 = V1;
-- V1(1) = 2.0; // the vector V2 will not be modified.
--
-- The Exception RangeError is raised when trying to access outside
-- the range of a vector :
-- V1(11) = 0.0 // --> will raise RangeError;
--
-- The Exception DimensionError is raised when the dimensions of two
-- vectors are not compatible :
-- math_Vector V3(1, 2);
-- V3 = V1; // --> will raise DimensionError;
-- V1.Add(V3) // --> will raise DimensionError;
-- A Vector can be constructed with a a pointer to "c array".
-- It allows to carry the bounds inside the Vector.
-- Exemple :
-- Standard_Real tab1[10];
--
-- math_Vector A (tab1[0], 1, 10);
-- Vector values may be initialized and
-- obtained using indexes which must lie within the range
-- definition of the vector.
-- Vector objects follow "value semantics", that is, they
-- cannot be shared and are copied through assignment.
-- Note: the overview of the Vectors and Matrices
-- component illustrates these properties on vectors.
