WhileDoElse control node doesn't work with 2 children

[benjinne]

BehaviorTree.CPP/src/controls/while_do_else_node.cpp

Line 36 in 16763c8

throw std::logic_error("WhileDoElse must have either 2 or 3 children");

Is thrown with only 2 children present

BehaviorTree.CPP/src/controls/while_do_else_node.cpp

Line 34 in 16763c8

if(children_count != 3)

Is there something I'm missing?

I will change this to "WhileDoElse must have 3 children"

FYI the documentation still refers to "either 2 or 3 children" https://github.com/BehaviorTree/BehaviorTree.CPP/blob/master/include/behaviortree_cpp_v3/controls/while_do_else_node.h#L21
