Detailed Description

The SimpleConditionNode provides an easy to use ConditionNode. The user should simply provide a callback with this signature.

BT::NodeStatus functionName(void)

This avoids the hassle of inheriting from a ActionNode.

Using lambdas or std::bind it is easy to pass a pointer to a method. SimpleConditionNode does not support halting, NodeParameters, nor Blackboards.
