    Add dragonflow model printers - first stage

    Add a parser for the dragonflow model and allow printing the model to
    stdout. In the next stages we want to add different representations as
    well: e.g. jsonschema, UML, etc.
    This is a standalone app, currently not taking any argument. We will add
    arguments in the future when more parsers will be added.

    Modified the parsing to be more memory efficient

    Removed the intermediate structure used during parsing. The printer now
    does not need to be aware of the model structure.
    The parser does the iteration over the fields and allows the printer to
    have no logic at all (no looping through the fields).
    This also saves memory and time as we do not re-create the whole model
    in our new structure, but rather go over the model only once.
    The EmbeddedField was not handled correctly.
    Add correct handling for it.
