 /**
  * Parses given XML node and extracting info about from where to
  * take parameters for user's models methods.
  * Additionally, it filters and re-arrange this data to give more
  * flexibility to the models design.
  *
  * Base syntax is 
  * <pre><code>
  * <param from="p2" count="2" offset="1">
  *		<filter>int</filter>
  * </param>
  * </code></pre>
  *
  * It takes two parameters ("count" attribute), starting from 
  * the second ("offset" attribute). Indexing is zero-based.  
  * Then, received values  might be passed to, for example, dataset as first and second parameters.
  * Besides, {@link Filter} int applies to each parameter. If parameters were 
  * strings, after applying they becomes NULL values.
  *
  * Offset and count attributes are valid only while retrieving "p2" parameters.
  *
  * Another example:
  * <pre><code>
  * <param from="p2" count="2" offset="1" as="array">
  *		<filter>array_int</filter>
  * </param>
  * </code></pre>
  *
  * Here "as" attribute was presented. If "as" equals to "array", than collected data will be
  * passed to the model's method as single parameter as int-indexed array. "array_int" 
  * filter will be applied to the obtained array. Applying "int" filter int this case will cause
  * to receiving a NULL value.
  *
  * To receive "p1" parameter, you should use this syntax:
  * <pre><code>
  * <param from="p1">
  *		<filter>int</filter>
  * </param>
  * </code></pre>
  *
  * Specifying "count" and "offset" attributes will give no effect. There is single "p1" parameter.
  * It also may be filtered.
  *
  * System allows you to retrieve certain $_GET parameters. To do so use such syntax:
  * <pre><code>
  * <param from="p3" var="q">
  *		<filter>int</filter>
  * </param>
  * </code></pre>
  *
  * For example, if current url is <code>http://example.com/index.html?q=123</code>, value "123" will be
  * passed to the model's method.
  *
  * If you want to pass some constant value to the method (ie some flag), use syntax:
  * <pre><code>
  * <param constant="1">
  * </param>
  * </code></pre>
  *
  * Internal pagination system could pass predicted 'from' and 'limit' values to the model.
  * Use:
  * <pre><code>
  * <param from="limit">
  * </param>
  * </code></pre>
  * In this case, <code>array("from"=>$from, "limit"=>$limit)</code> will be passed.
  *
