2.0.0

breaking changes

endpoint

• Made endpoint non movable. #79.
  • It is designed non copyable and non movable but the code was able to movable invalidly,
    so this is a bug fix. However some of test, broker, and bench code had been used move constructor.
    Hence I categolize the fix to breaking changes.

broker

• Fixed endpoint's internal queue operation. #66
• Refined documents. #62
• Refined examples. #61
