/**
* Helper function that returns the multiple serialized DataTable of the given PHP array.
* The DataTable here associates a subtable to every row of the level 0 array.
* This is used for example for search engines. Every search engine (level 0) has a subtable containing the
* keywords.
*
* The $arrayLevel0 must have the format
* Example: array (
* LABEL => array(col1 => X, col2 => Y),
* LABEL2 => array(col1 => X, col2 => Y),
* )
*
* The $subArrayLevel1ByKey must have the format
* Example: array(
* LABEL => #Piwik_DataTable_ForLABEL,
* LABEL2 => #Piwik_DataTable_ForLABEL2,
* )
*
*
* @param array $arrayLevel0
* @param array of Piwik_DataTable $subArrayLevel1ByKey
* @return array Array with N elements: the strings of the datatable serialized
