Detailed Description

The ShiftedToken class inherits from Token and describes tokens which have a gap in addition of the multiplicative factor. This kind of token allows the description of linear functions which do not pass through the origin, of the form :

y = ax +b

where <x> and <y> are the unknown variables, the mutiplicative factor, and the gap relative to the ordinate axis.

An example is the translation between the Celsius and Fahrenheit degree of temperature.
