- ConfigObject: add support for 64-bits integers and OKS class reference
types:
- 64 bits signed integer type: int64_t
- 64 bits unsigned integer type: uint64_t
- class reference: std::string
- Split existing ERS macros on declaration and implementation parts: this
fixes implementation bugs linking C++ code with Java and Python
