This method explicitly adds a new property to this wwDynamic instance and it automatically adds the property to the __PropertyNameOverrides list which is used during JSON serialization to produce properly cased serialization output.

The primary use case for this method is:

• If you need to preserve property name case for JSON Serialization
• If you need better performance for adding properties
• Set properties with internal FoxPro base class names:
  Name, Class, Tag, Parent etc.

Here are some examples that demonstrate:

loMessage = CREATEOBJECT("wwDynamic")

*** Create a name property
loMessage.name = "Rick"

*** same as (no benefit since name is already lower case always)
loMessage.AddProp("name","Rick")

*** This has benefit of supporting mixed cases via __PropertyNameOverrides
loMessage.AddProp("lastName","Strahl")

*** This loses mixed case for property name serialization
loMessage.lastName = "Strahl"

This method has a funky name of AddProp() as it cannot have the same name as AddProperty() which is a base class method that can't be completely overridden. Hence the alternate name to avoid the base class firing and failing on creation of FoxPro reserved properties.
