//////////////////////////////////////////////////////
//
// LuaConsole:
//
// Used to parse commands that are being interactively typed
// in by a user. The common usage pattern is:
//
// 1. Print the prompt suggested by 'get_prompt'.
// 2. Read a line of text from stdin.
// 3. Add the line to the LuaConsole using 'add'.
// 4. Get the command word using get_command.
// 5. If the command is empty, do nothing.
// 6. If the command is nonempty, get the args and execute it.
//
// The LuaConsole expects you to type a lua command, or one
// of the following slash-commands:
//
// /quit - exit the program
// /view - display the nearby tangibles
// /menu [tanid] - display the menu for tangible
// /tick [timevalue] - advance the simulation clock
// /choose [number] - choose menu item number
// /1234 - choose menu item 1234
//
// If you type anything else, the LuaConsole will generate a
// syntax error. Note that not all of the commands above are
// supported in all interpreters.
//
// Lua commands can be one of the following:
//
// <expression> - invoke "<expression>""
// = <expression> - invoke "return <expression>"
// ? <expression> - probe "<expression>"
// ?= <expression> - probe "return <expression>"
//
// Once a command has been typed (or a syntax error has been
// typed), the LuaConsole will return the command. The command
// can be fetched using command(), int_arg(), and str_arg()
//
