motivation

1. I want a pointcloud type that can be inited with any amount of dims
   for instance :
   3 dims : x, y, z
   4 dims : x, y, z, time or intensity or gray scale ...
   even a pointcloud with ORB descriptor (optional)

2. I want a pointcloud type that i can define channels (even dynamicly) and I can easily access any channel data with operator[] or something like .at("channel name")

3. I want it to be thread-safe and lock free

Todos

• benchmark on std::vector vs tbb::concurrent_vector vs pcl
• parallel transform on pointcloud
• parallel filtering
