 Providing a memory efficient way for message conversion while allowing user defined types without the cost of iterations.
+Instead of converting the entire cloud into a `Vec`, you get an iterable type that converts each point from the message on the fly.
 
-Instead of converting the entire cloud into a `Vec`, you get an `Iterator` that converts each point from the message on the fly.
-An example for using this crate is [this filter node](https://github.com/stelzo/cloudfilter). It is also a good starting point for
