/**
 * We support insert in 3 ways here:<br>
 * 
 * <pre>
 *      1- if no partitioning requirement is found:
 *          the insert will be delegated to the default insert behavior of {@link SqlMapClientTemplate};
 *      2- if partitioning support is enabled and 'parameterObject' is NOT a type of collection:
 *          we will search for routing rules against it and execute insertion as per the rule if found, 
 *          if no rule is found, the default data source will be used.
 *      3- if partitioning support is enabled and 'parameterObject' is a type of {@link BatchInsertTask}:
 *           this is a specific solution, mainly aimed for "insert into ..values(), (), ()" style insertion.
 *           In this situation, we will regroup the entities in the original collection into several sub-collections as per routing rules, 
 *           and submit the regrouped sub-collections to their corresponding target data sources.
 *           One thing to NOTE: in this situation, although we return a object as the result of insert, but it doesn't mean any thing to you, 
 *           because, "insert into ..values(), (), ()" style SQL doesn't return you a sensible primary key in this way. 
 *           this, function is optional, although we return a list of sub-insert result, but don't guarantee precise semantics.
 * </pre>
 * 
 * we can't just decide the execution branch on the Collection<?> type of
 * the 'parameterObject', because sometimes, maybe the application does want
 * to do insertion as per the parameterObject of its own.<br>
