Detailed Description

A set of variable indexes. This is used to implement the set of power variables in a monomial or just a colletion of variable indexes (in this case the powers are not used).

Note that this is not a set of variables with information for each variable (see Tvariables) but merely a set of variable indexes.

This is basically a vector (see Tvector) and is not implemented using the generic Tvector just for legacy reasons (Tvariable_set was implemented much before that the generic structure Tvector). Moreover, to use a generic vector we need to implement a basic type including the variable identifier and the variable power (and the associated constructor, destructor, copy operator, etc).
