--[[-- This file contains some common command param parse functions;
this file is less of a config and more of a requirement but you may wish to change how some behave;
as such you need to be confident with lua but you edit this config file;
use Commands.add_parse('name',function(input, player, reject) end) to add a parse;
see ./expcore/commands.lua for more details
@config Commands-Parse
@usage Adds Parses:
    boolean
    string-options - options: array
    string-max-length - max_length: number
    number
    integer
    number-range - range_min: number, range_max: number
    integer-range - range_min: number, range_max: number
    player
    player-online
    player-alive
    force
    surface
