Antirez' Picol Tcl interpreter, as an STB-style single header library

	/**
	* This is a modified version of [Picol][],
	* Salvatore Sanfilippo ("antirez")'s Tcl interpreter in ~500 lines.
	*
	* This version turns it into a [STB][]-style single header library, so
	* that it can be embedded into another program as a command interpreter.
	*
	* To use it, add a `#define PICOL_IMPLEMENTATION` above the
	* `#include "picol.h"` in _one_ of your source files.
