Future meets Signal

• Future optimization - it may be a little faster now and have slightly more readable stack trace.
• Future renames - some handlers may have different names to be more consistent across all codebase
• debug system remove - debug logs in proposed form were not as useful as it should, stay tuned for a new approach
• Better documentation coverage - just always good
• Adding Signals - meet a brand new way of dealing with continuous streams of data
• minor fixes, improvements
