	'' @SDESCRIPTION:	generates a representation of a name value pair in JSON grammer
	'' @DESCRIPTION:	It generates a name value pair which is represented as <em>{"name": value}</em> in JSON.
	''					the generation is fully recursive. Thus the value can also be a complex datatype (array in dictionary, etc.) e.g.
	''					<code>
	''					<%
	''					set j = new JSON
	''					j.toJSON "n", array(RS, dict, false), false
	''					j.toJSON "n", array(array(), 2, true), false
	''					% >
	''					</code>
	'' @PARAM:			name [string]: name of the value (accessible with javascript afterwards). leave empty to get just the value
	'' @PARAM:			val [variant], [int], [float], [array], [object], [dictionary]: value which needs
	''					to be generated. Conversation of the data types is as follows:<br>
	''					- <strong>ASP datatype -> JavaScript datatype</strong>
	''					- NOTHING, NULL -> null
	''					- INT, DOUBLE -> number
	''					- STRING -> string
	''					- BOOLEAN -> bool
	''					- ARRAY -> array
	''					- DICTIONARY -> Represents it as name value pairs. Each key is accessible as property afterwards. json will look like <code>"name": {"key1": "some value", "key2": "other value"}</code>
	''					- <em>multidimensional array</em> -> Generates a 1-dimensional array (flat) with all values of the multidimensional array
	''					- <em>request</em> object -> every property and collection (cookies, form, querystring, etc) of the asp request object is exposed as an item of a dictionary. Property names are <strong>lowercase</strong>. e.g. <em>servervariables</em>.
	''					- OBJECT -> name of the type (if unknown type) or all its properties (if class implements <em>reflect()</em> method)
	''					Implement a <strong>reflect()</strong> function if you want your custom classes to be recognized. The function must return
	''					a dictionary where the key holds the property name and the value its value. Example of a reflect function within a User class which has firstname and lastname properties
	''					<code>
	''					<%
	''					function reflect()
	''					.	set reflect = server.createObject("scripting.dictionary")
	''					.	reflect.add "firstname", firstname
	''					.	reflect.add "lastname", lastname
	''					end function
	''					% >
	''					</code>
	''					Example of how to generate a JSON representation of the asp request object and access the <em>HTTP_HOST</em> server variable in JavaScript:
	''					<code>
	''					<script>alert(<%= (new JSON)(empty, request, false) % >.servervariables.HTTP_HOST);</script>
	''					</code>
	'' @PARAM:			nested [bool]: indicates if the name value pair is already nested within another? if yes then the <em>{}</em> are left out.
