- add classes inside app/library for creting Tethys xml: Field.ts, Strategy.ts, XmlModel.ts

- added model DocumentXmlCache.ts
- npm updates
- changed all models inside app/Models to use corrected BaseModel.ts
- added extra extension class DatasetExtension.ts for app/dataset.ts for caching internal and external fields

app/Models/DocumentXmlCache.ts
