Here are the packages with brief descriptions (if available):

[detail level 12]

▼NCoreLink
CConfig	The Config class is filled once at the beginning of the unity session and contains important server information
CControl	Singleton class to communicate with Corelink
CControlStream	Abstract class for a control stream that contains the function prototypes for the server callback functions. Inherited by CorelinkTCP and CorelinkWebSocket. CorelinkWebSocket must have a child class called ControlCallBacks that can override these server callback functions
CCorelinkException
CCorelinkParser	This class is a purely static utility class that contains helper functions for CoreLink data parsing
CCorelinkTCP	This class was used as the control connection which will be deprecated soon in favor of WebSockets
CCorelinkUDP	Client to send and receive data to/from CoreLink via UDP
CCorelinkWebSocket
CCredentials	Contains user information to authenticate with Corelink. The username and password are sent to the server and authenticated, and then the server returns a token which must be used throughout the app's life to authenticate every function request
CReceiverStream	Parent class to custom receiver scripts that will be attached to GameObjects. Several of these can be instantiated, and each of them will have their own sender stream. OnMessage(streamID, data) is called whenever there is data See the README for caveats on multiple receiver streams
CReceiverStreamParams
CSenderStream	Parent class to custom sender scripts that will be attached to GameObjects. Several of these can be instantiated. Use Send(streamID, data) to send data
CSenderStreamParams	Contains all the necessary parameters for sender streams except IP and port. Inherits from StreamParams
CStreamFilter	When creating a receiver stream, the request must query what workspace and type of stream to receive from. This class is a wrapper to create a filter to create receiver streams. At least 1 workspace and 1 type are required. Streamids can be left blank
CStreamParams	Parent class of Receiver/SenderStreamParams with shared information
CUDPHeader	Header for a UDP packet to Corelink. Contains the streamID and timestamp in milliseconds since the Unix Epoch
CUdpState	Utility class for asynchronous data receiving
▼NCorelink
CTransformPasser	This class is a utility class to serialize the unity Transform class in order to pass/retrieve to/from corelink
