The use of InertialPose3

[saparkison]

I'm having trouble figuring out how to use the IntertialPose3 type. Sorry if I am missing an obvious example. I see /test/testInertialPose3.jl but following that approach doesn't seem to work anymore. I get an error with addVariable!()

ERROR: LoadError: MethodError: no method matching addVariable!(::GraphsDFG{SolverParams, DFGVariable, DFGFactor}, ::Symbol, ::Type{InertialPose3}; N=100)

which I think comes down to InertialPose3 <: InferenceVariable evaluating as false

Am I missing something? Or is there a better example of how to use InertialPose3?

Thanks!
