Merge features from nem2-library-js into reference SDK #61
Description
The SDK reference implementation of the SDKs should not base on the nem2-library source code anymore.
Features which are implemented in the library and used in the SDK include, but are not limited to:
- Swagger API models
- DTO models
- Catapult keypairs generation
- UInt64 implementation
- Serialization utilities
- Transaction type classes
These features have been developed in the library in a first version but should now get merged in the reference SDK implementation since those will also be needed in later implemented SDKs.
Regarding serialization utilities, please do not start importing work on this side since we will be using the catbuffer tool when it is available.
