- Added a new data type self, that represent the id of the intity itself
- Fixed multi threading for parsing, now each thread use it's own writer
and I concat them at the end
- Added a schemaStruct id to the list
- Other fixe and stuff to go with the rest

New step, multi threading for all function then finally relationship
