Multi Static Camera Yaml

[Levi-Armstrong]

Should I change the Yaml such that the camera data is a vector instead of having the pass the number of cameras?

I'm in favor of anything that reduces the number of potential mistakes we can make.

On a side note, I'd like to adopt string parsing logic similar to that found in URDF files: Namely, I want to understand URI's like file or package so we can load files relative to our ROS workspaces and don't require absolute paths.
