[octree] "Using more than one type of container in octree construction"

Multiple type of octree's and octree's container are implemented, but anyone cover all need of my problem.

Context
I am doing a project that involves use of PCA in all the points inside each leaf voxel of the tree. After that, I have to seach in the neighboor leaf voxels to find some similarity.

Expected behavior

The expected behavior is to use only one type of octree and do both operations, PCA and Voxel Search.

Current Behavior

Even using to types of octree, the trees are not exactly the same. So, with the structures that PCL have implemented i can do just one of the operations.

Describe the solution you'd like

An explanation of what i can do to solve the problem, using the PCL structures or even implementing my one.

Describe alternatives you've considered

I've considered to implement my own octree extending OctreePointCloud, but I need an explanation before do this step.

Thanks.

Start by comparing the PCL octree and container structures mentioned in the issue, especially OctreePointCloud, and trace how each supports PCA over leaf voxels versus neighboring-voxel search. Determine whether one existing structure can support both operations or whether the request requires a new design. Done means providing a documented, technically supported approach with clear limitations.
