/**
* @class lsl_streaminfo
* Handle to a stream info object.
*
* Stores the declaration of a data stream.
* Represents the following information:
*
* - stream data format (number of channels, channel format)
* - core information (stream name, content type, sampling rate)
* - optional meta-data about the stream content (channel labels, measurement units, etc.)
*
* Whenever a program wants to provide a new stream on the lab network it will typically first
* create an lsl_streaminfo to describe its properties and then construct an #lsl_outlet with it to
* create the stream on the network. Other parties who discover/resolve the outlet on the network
* can query the stream info; it is also written to disk when recording the stream (playing a
* similar role as a file header).
