Error when no dotted timeout in .yaml configuration file

[RafaelRey]

I found that when launching the twist_mux node with timeout parameter as follow(config.yaml):

topics:

name : navigation
topic : nav_vel
timeout : 5
priority: 10

The node throw:

setting /run_id to d5633268-ee5c-11e9-923c-b8aeed7a6236
process[rosout-1]: started with pid [2691]
started core service [/rosout]
process[twist_mux-2]: started with pid [2694]
terminate called after throwing an instance of 'XmlRpc::XmlRpcException'
[twist_mux-2] process has died

The solution is to change 5 to 5.0. It's not an important issue but I spent some time trying to find out what happen. I also think that the problem does not come at all from the node, instead of the .yaml parser or something related to the .yaml reading, but not sure.
