    Description

    Get can be used to retrieve a value by name. If an element with name equal to AName exists, and its type corresponds to the type of the ADefault, then the value is returned. If no element element with the correct type exists, the ADefault value is returned.

    If no default is specified, the value is returned as a variant type, or Null if no value was found.

    The other value retrieval properties such as Integers, Int64s, Booleans, Strings, Floats, Arrays, and Objects will raise an exception if the name is not found. The Get function does not raise an exception.
