/**
 * @public
 * @class QueryInsert
 *
 * @description
 * For design reasons this class should not be used directly. Use this class with {@link Insert} function.
 * Prefer use of save() method instead of Insert for a single entry.
 * Insert optimize multiple entry insertion with bulk mecanisme for example.
 *
 * @param T @extends DbHelperModel a model declared with table and column annotations
 *
 * @example
 * ```typescript
 * // Create new model instance
 * const todo = new Todo();
 * // manipulates todo instance and then insert it
 * Insert(todo).exec().subscribe((qr: QueryResult<any>) => {
 *      // do something after insertion
 * }, (err) => {
 *      // manage error
 * });
 *
 * // it is simplier to use the save methode for a single entry
 * todo.save()
 *
 * // Insertion should be used for multiple model insertion
 * const todos = <Todo[]>[];
 * // provide and edi.subscribe((qr: QueryResult<any>) => {
 *      // do something after insertion
 * }, (err) => {
 *      // manage error
 * });t new entries
 * Insert(todos).exec().subscribe((qr: QueryResult<any>) => {
 *      // do something after insertion
 * }, (err) => {
 *      // manage error
 * });
 * ```
