gModel is a virtual class from which all other model classes will inherit. Model objects will be responsible for storing and updating the data sets.

A virtual Class: No objects may be created from it.

modelData:: the actual model data
linkData:: a list of the functions to link this data to its parent and child models (if it has any)
virtualData:: data that pertains to the views of this model
modelName:: the name of the model (will be the same name as the MVC)
modelVar:: a list of variables that refer to the modelData (for instance this may be t-test values that were calculated from the modelData)

linkData<-: Sets the linkData slot
linkData: Returns the linkData slot
modelData<-: Sets the modelData slot
modelData: Returns the modelData slot
modelName<-: Sets the modelName slot
modelName: Returns the modelName slot
virtualData<-: Sets the virtualData slot
virtualData: Returns the virtualData slot
modelVar<-: Sets the modelVar slot
modelVar: Returns the modelVar slot

Also, all models will have an updateModel method that will be defined in the packages that use this package (for example, iSPlot and iSNetwork). The updateModel method will be called by a gUpdateDataMessage object when the data needs to be updated. Another method that may be defined for certain models is the provideInfo method that will return model information when it is asked for by a gAskAncestorMessage object.
