    Usage:
    * Make an empty GameObject
    * "Add Component" a Phalanx
    * Drop in your Avatar Descriptor
    * Click "Get Data From Avatar"
    * Get your Avatar ID from the pipeline component beneath the avatar descriptor
    * Optionally: Set up a thumbnail and an overlay text to superimpose onto it dynamically

// These tables differ from the original paper (Marching Cubes: A High Resolution 3D Surface Construction Algorithm)
//
// The co-ordinate system has the more convenient properties:
//
//    i = cube index [0, 7]
//    x = (i & 1) >> 0
//    y = (i & 2) >> 1

Haxe FrontEnd

Reads haxelib-lock.json (if exists)

Reads <file> (if called with -lock-file <file>) which will partially override haxelib-lock.json

Takes arguments (hxml files or anything else)

Expand hxml files to their actual content

--server-connect

Haxe 4.0 introduces a new way of communicating IDE and the compiler.

Here's what an IDE needs to do:

• start a TCP server on some port (can pass 0 to bind to any available one)
• start haxe --server-connect <port> where <port> is replaced with the port number the started TCP server was bound to.
• haxe will connect to that server and await requests, ensure that happens
• send messages of the following structure:
