/**
 * This is a "mashup" test for combining the two JSON types, the goal is to make
 * it work similarly to how the processing XML library works.
 * 
 * loadJSON(); should be able of returning both types of objects, and to do that
 * without having the typecast you need to combine the two classes somehow.
 * 
 * The way you use this is calling JSON.loadJSON("filename"); (or similar) and
 * then the class will maintain the type of object it is (either array or
 * object) and simply forward the requests the user does to the correct class...
 * of course making sure that the type is of correct class! You shouldn't be
 * able of calling ".get(index)" on an JSONObject for example... it should then
 * notify the user by a simple text message to the console.

	/**
	 * 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 <code>get</code> and <code>opt</code> methods for accessing the
	 * values by name, and <code>put</code> methods for adding or replacing values
	 * by name. The values can be any of these types: <code>Boolean</code>,
	 * <code>JSONArray</code>, <code>JSONObject</code>, <code>Number</code>,
	 * <code>String</code>, or the <code>JSONObject.NULL</code> object. A JSONObject
	 * constructor can be used to convert an external form JSON text into an
	 * internal form whose values can be retrieved with the <code>get</code> and
	 * <code>opt</code> methods, or to convert values into a JSON text using the
	 * <code>put</code> and <code>toString</code> methods. A <code>get</code> method
	 * returns a value if one can be found, and throws an exception if one cannot be
	 * found. An <code>opt</code> method returns a default value instead of throwing
	 * an exception, and so is useful for obtaining optional values.
	 * <p>
	 * The generic <code>get()</code> and <code>opt()</code> methods return an
	 * object, which you can cast or query for type. There are also typed
	 * <code>get</code> and <code>opt</code> methods that do type checking and type
	 * coercion for you. The opt methods differ from the get methods in that they do
	 * not throw. Instead, they return a specified value, such as null.
	 * <p>
	 * The <code>put</code> methods add or replace values in an object. For example,
	 *
	 * <pre>
	 * myString = new JSONObject().put(&quot;JSON&quot;, &quot;Hello, World!&quot;).toString();
	 * </pre>
	 *
	 * produces the string <code>{"JSON": "Hello, World"}</code>.
	 * <p>
	 * The texts produced by the <code>toString</code> methods strictly conform to
	 * the JSON syntax rules. The constructors are more forgiving in the texts they
	 * will accept:
	 * <ul>
	 * <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
	 * before the closing brace.</li>
	 * <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
	 * quote)</small>.</li>
	 * <li>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:
	 * <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers and
	 * if they are not the reserved words <code>true</code>, <code>false</code>, or
	 * <code>null</code>.</li>
	 * <li>Keys can be followed by <code>=</code> or <code>=></code> as well as by
	 * <code>:</code>.</li>
	 * <li>Values can be followed by <code>;</code> <small>(semicolon)</small> as
	 * well as by <code>,</code> <small>(comma)</small>.</li>

	/**
	 * A JSONArray is an ordered sequence of values. Its external text form is a
	 * string wrapped in square brackets with commas separating the values. The
	 * internal form is an object having <code>get</code> and <code>opt</code>
	 * methods for accessing the values by index, and <code>put</code> methods for
	 * adding or replacing values. The values can be any of these types:
	 * <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
	 * <code>Number</code>, <code>String</code>, or the
	 * <code>JSONObject.NULL object</code>.
	 * <p>
	 * The constructor can convert a JSON text into a Java object. The
	 * <code>toString</code> method converts to JSON text.
	 * <p>
	 * A <code>get</code> method returns a value if one can be found, and throws an
	 * exception if one cannot be found. An <code>opt</code> method returns a
	 * default value instead of throwing an exception, and so is useful for
	 * obtaining optional values.
	 * <p>
	 * The generic <code>get()</code> and <code>opt()</code> methods return an
	 * object which you can cast or query for type. There are also typed
	 * <code>get</code> and <code>opt</code> methods that do type checking and type
	 * coercion for you.
	 * <p>
	 * The texts produced by the <code>toString</code> methods strictly conform to
	 * JSON syntax rules. The constructors are more forgiving in the texts they will
	 * accept:
	 * <ul>
	 * <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
	 * before the closing bracket.</li>
	 * <li>The <code>null</code> value will be inserted when there is <code>,</code>
	 * &nbsp;<small>(comma)</small> elision.</li>
	 * <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
	 * quote)</small>.</li>
	 * <li>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:
	 * <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers and
	 * if they are not the reserved words <code>true</code>, <code>false</code>, or
	 * <code>null</code>.</li>
	 * <li>Values can be separated by <code>;</code> <small>(semicolon)</small> as
	 * well as by <code>,</code> <small>(comma)</small>.</li>
	 * </ul>
