## Class "gUpdateDataMessage": A class to represent an update data message

### Description

gUpdateDataMessage is a class to represent an update data message. gUpdateDataMessage is inherited from the virtual class, gUpdateMessage. Whenever a gUpdateDataMessage is created (initialized), the next step is to call the handleMessage method to act upon that message and update the data.

### Objects from the Class

Objects can be created by calls of the form `new("gUpdateDataMessage", ...)`. The initialize method for this class will be created in other packages that use this package (for example, the initialize method will be created in the iSNetwork and iSPlot packages).
