Suspicious shared_ptr

[versatran01]

May be I'm wrong, but all those

pub_temp = nh.advertise<sensor_msgs::Temperature>("temperature", 1);
pub_temp_ptr = boost::shared_ptr<ros::Publisher>(&pub_temp);

look very suspicious/dangerous to me.

One workaround is to use a custom null deleter. Or maybe just use plain pointer?

A plain pointer should be sufficient since it'll have the same scope as the object here.
