  writes to options field of aura data, which is then read to construct the user config panel

  Values in aura data:
  authorOptions -> array of options.
  config -> key/value hash table.
    key, and format of value are defined by author, and the precise value is defined by the user.
    This table gets copied into the aura's script environment via aura_env.config.
  authorMode -> bool, used to determine if author or user mode is displayed in Custom Options tab.

  option -> table with fields:
    type (required) -> string such as "toggle", "slider", "string", "number", "color", etc.
    key (required) -> string which custom scripts can use to read the selected option
    default (required) -> default value of the option
    name (required) -> displayed name in the user config panel
    width (required) -> number between 0.1 and 2 (softMin of 0.5). Determines the width of the option.
    useDesc (optional) -> bool. If false, then the tooltip will not be used.
    desc (optional) -> string to be displayed in the option tooltip
  When options are merged together (i.e. when the user multiselects and then opens the custom options tab), there is one additonal field:
    references -> childID <=> optionID map, used to dereference to the proper option table in setters
  Supported option types, and additional fields that each type supports/requires:
    group -> represents a group of options.
      useCollapse (optional) -> if true, then group will have a collapsible header in user mode.
      collapse (optional) -> whether or not the collapsible header begins collapsed when the user begins a session.
      subOptions (required) -> array of options
      groupType (required) -> type of group:
        simple -> group is for organizational purposes only.
                  config value is a sub config
        array -> group represents an array of entries from the user, with similar information between them:
                 config value is arranged as an array of sub configs, one for each entry in the array.
          limitType (required) -> Specifies if user can add or remove entries from the array freely
          size (optional) -> required if the limitType is not "none".
    description -> dummy option which can be used to display some text. Not interactive, and so key/default/name are not set or required.
      text (required) -> text displayed on the panel
      fontSize (optional) -> fontSize. Default is medium.
    space -> dummy option which acts as a spacer. Not interactive, and so key/default/name are not set or required.
      useWidth (required) -> bool. If false, then the space is given full width in AceConfig. Else, option.width is used.
      useHeight (required) -> bool. If false, then the space covers only the line it renders on. Else, it covers the number of lines specified.
      height (optional) -> number. Height of space, in lines.
    separator -> AceConfig header widget.
      useName (required) -> bool. If true, then option.text is used as the name.
      test (optional) -> string. Text to be shown on the header widget.
    input -> text field which the user can input a string.
      length (optional) -> allowed length of the string. If set, then input longer than the allowed length will be trimmed
    number -> text field which the user can type in a number. Input is converted to a number value.
      max (optional) -> maximum allowed value. If set, then input greater than the maximum will be clamped
      min (optional) -> minimum allowed value. If set, then input lesser than the minimum will be clamped
      step (optional) -> stepsize
    select -> dropdown menu with author-specified strings to select.
      values (required) -> array of strings to select. config value will be the index corresponding to the string.
    toggle -> checkbutton which can be in a state of true or false, corresponding to checked and unchecked
    color -> color selector. Color is delivered as an {r, g, b, a} array.
    range -> slider element which allows the user to select a number value.
      max (optional) -> maximum allowed value. If set, then input greater than the maximum will be clamped
      min (optional) -> minimum allowed value. If set, then input lesser than the minimum will be clamped
      softmax (optional) -> Like max, but the manual entry will accept values up to the softmax.
      softmin (optional) -> Like min, but the manual entry will accept values down to the softmin.
      bigStep (optional) -> step size of the slider. Defaults to 0.05
      step (optional) -> like bigStep, but applies to number input as well
