A dimension of the vector space.
An object of the class Variable represents a dimension of the space, that is one of the Cartesian axes. Variables are used as basic blocks in order to build more complex linear expressions. Each variable is identified by a non-negative integer, representing the index of the corresponding Cartesian axis (the first axis has index 0).

Sets the variable stringifier object.
A variable stringifier object provides customization for the toString method; if no variable stringifier object is set (or if it is set to a null refeerence value), the PPL default variable output function will be used.
