Detailed Description

This class allows to create IGES Entities in a literal form : their definition is free, but they are not recognized as instances of specific classes.

This is a way to define test files without having to create and fill specific classes of Entities, or creating an IGES File ex nihilo, with respect for all format constraints (such a way is very difficult to run and to master).

This class has the same content as an UndefinedEntity, only it gives way to act on its content
