These functions help in adding, modifying or removing variable definitions 
in a configuration object obtained with ConfigFileOpen or 
ConfigFileCreate. ConfigEditDefinition() will add the 
definition if not existing.
ConfigEditDefinition(configuration, name, value, confirm = TRUE)
ConfigRemoveDefinition(configuration, name)
configuration | 
 Configuration object obtained wit ConfigFileOpen() or ConfigFileCreate().  | 
name | 
 Name of the variable to add/modify/remove.  | 
value | 
 Value to associate to the variable.  | 
confirm | 
 Flag to stipulate whether to ask for confirmation if the variable is being modified. Takes by default TRUE.  | 
A modified configuration object is returned.
