 Constructor. Types must be defined using defineType() before variable can be used

 Copy constructor

 Destructor

 Set value by specifying the index code of the desired state.
 If printError is set, a message will be printed if
 the specified index does not represent a valid state.

 Set value by specifying the name of the desired state
 If printError is set, a message will be printed if
 the specified label does not represent a valid state.

 Define a state with given name, the lowest available
 positive integer is assigned as index. Category
 state labels may not contain semicolons.
 Error status is return if state with given name
 is already defined

 Define a state with given name and index. Category
 state labels may not contain semicolons
 Error status is return if state with given name
 or index is already defined
