Naming, headers, and declaration changes to match style guide

[bsutherland333]

I did some cleaning and refactoring of ROSplane:

• Matched all class, enum, struct, member variables, and function names to match ROSflight style guide
• Organized includes to match ROSflight style guide and removed unused ones
• Removed various unnecessary declarations/initializations
• Fixed a wild bug where a namespace was being opened and closed in separate files

Looks thorough!

@iandareid did you want me to merge this in now, or wait?

[iandareid]

I think perhaps we should wait. I know that the refactor of the EKF may create large conflicts. What do you think @bsutherland333?

[bsutherland333]

We can wait. I'll let you merge it in when you'd like. But I don't want to do this twice xD.

[bsutherland333]

@iandareid Is the EKF refactoring on a branch somewhere? Maybe what we should do is I can deconflict the EKF changes as they are now and then merge the refactoring in before.

Ok I got a plan for deconfliction, just let me know when the EKF refactoring is pushed and I'll update it 😎
