Major update:

- 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
