      public class JSONObject
      extends java.lang.Object
      implements JSONElement, java.util.Map

  A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names. The internal form is an object having `get` and `opt` methods for accessing the values by name, and `put` methods for adding or replacing values by name. The values can be any of these types: `Boolean`, `JSONArray`, `JSONObject`, `Number`, or `String`. A JSONObject constructor can be used to convert an external form JSON text into an internal form whose values can be retrieved with the `get` and `opt` methods, or to convert values into a JSON text using the `put` and `toString` methods. A `get` method returns a value if one can be found, and throws an exception if one cannot be found. An `opt` method returns a default value instead of throwing an exception, and so is useful for obtaining optional values.

  The generic `get()` and `opt()` methods return an object, which you can cast or query for type. There are also typed `get` and `opt` methods that do type checking and type coersion for you.

  The `put` methods adds values to an object. For example,

           myString = new JSONObject().put("JSON", "Hello, World!").toString();

  produces the string `{"JSON": "Hello, World"}`.

  The texts produced by the `toString` methods strictly conform to the JSON sysntax rules. The constructors are more forgiving in the texts they will accept:
  - An extra `,` (comma) may appear just before the closing brace.
  - Strings may be quoted with `'` (single quote).
  - Strings do not need to be quoted at all if they do not begin with a quote or single quote, and if they do not contain leading or trailing spaces, and if they do not contain any of these characters: `{ } [ ] / \ : , = ; #` and if they do not look like numbers and if they are not the reserved words `true`, `false`, or `null`.
  - Keys can be followed by `=` or `=>` as well as by `:`.
  - Values can be followed by `;` (semicolon) as well as by `,` (comma).
  - Numbers may have the `0-` (octal) or `0x-` (hex) prefix.
  - Comments written in the slashshlash, slashstar, and hash conventions will be ignored.
