- Logging
- Created LogCore Class
- Updated LogCore to use file descriptors instead of stdout
- Add Log object reference to constructors for:
FunctionCore, SelectCore
- Use extern Log() object in SignalCore
- SelectableCore
- Added new connection type: ForkedPipe
Create pipe, fork process, connect pipe out to child stdin, exec
