GenerateVE4Variable

 Generate vague environment for a linguistic variable (partition).

 function Variable=GenerateVE4Variable(Variable,params)

 -------------------------------------------------------------------------
 Parameters
 -------------------------------------------------------------------------
 Variable - linguistic variable as it is described in a FIS structure
    |-name
    |-range
    |-(RangeLength) it is present only if the partition is normalized
    |-(Offset)      it is present only if the partition is normalized
    |-mf(j)--name
           |-type
           |-params
           |-paramsy

           |-RPy
 params - structure containing information about the parameters of the 
    |     method.
    |-InterpolationType    VEIN or FIVE
    |-RPtype               only corecentre is allowed
    |-NumOfPoints  size (resolution) of the antecedent, consequent universes 
    |-ShepardPower power factor in the Shepard interpolation formula
    |-NLS          optional, if not given: linear scaling function approximation
                   if given: NLS is the constant factor of sensitivity for
                   neighbouring scaling factor differences in nonlinear
                   scaling function approximation
