simple_actions

A simple version of the rclpy/rclcpp action libraries.

Key Design Principles

For use with simple situations where there will never be two active goals.
Made for people like me who can't think about the future for too long without their head hurting.
Callbacks/methods should deal with the regular Goal/Feedback/Result methods, not wrapped versions.
If the Action Client does not connect to the server relatively quickly, a warning should be printed while it waits, and another message should report when it finally does connect.
