m = pwAddS(m, *ID, *value, fitSetting, minValue, maxValue, unit, name,
            description, usedInTimeTransformation)
 m = pwAddS(m, interactive)

 Adds an observation parameter to a model, i.e. a parameter which
 only occurs within one or more model observables Y and not within
 the reaction network or differential equations directly.
 Often, an observation parameter scales between measurement units
 and model units. Therefore, observation parameters are sometimes
 called scaling parameters.


Arguments for pwAddS

 ID            ID
 value         float   Default 1
 fitSetting    string  'global', 'local' (default), or 'fix'
 minValue      float   minimal value during fitting
 maxValue      float   maximal value during fitting
 unit          string
 name          string  descriptive name
 description   string
 usedInTimeTransformation  bool  If true, the parameter is used in the
                                 time transformation of the model.
                                 See pwSetTimeTransformation.

 Alternative function call for interactive specification:
 interactive   bool    If true, the user is prompted to enter the properties
                       into a user interface.



 Often, the concentration of the observable players can not be measured directly,
 but through a scaling factor as for example with Western Blotting. The scaling
 parameters behave like dynamic parameters, but are related to a set
 of observations and can be fitted separately.

 All parameters which occur only in the observations should be
 specified using pwAddS and not pwAddK in contrast to dynamic parameters.



 m = pwAddS(m, 'scale_Erk_obs', 1.2, 'global', 0, 100);
 m = pwAddY(m, 'Erk_obs', 'scale_Erk_obs * Erk');
