-    /**
-     *    Given an array of data (usually from a CSV import) attempts to save that data to the db.
-     *    If $model_name ISN'T provided, assumes that this is a 3d array, with toplevel keys being model names,
-     *    next level being numeric indexes adn each value representing a model object, and the last layer down
-     *    being keys of model fields and their proposed values.
-     *    If $model_name IS provided, assumes a 2d array of the bottom two layers previously mentioned.
-     *    If the CSV data says (in the metadata row) that it's from the SAME database,
-     *    we treat the IDs in the CSV as the normal IDs, and try to update those records. However, if those
-     *    IDs DON'T exist in the database, they're treated as temporary IDs,
-     *    which can used elsewhere to refer to the same object. Once an item
-     *    with a temporary ID gets inserted, we record its mapping from temporary
-     *    ID to real ID, and use the real ID in place of the temporary ID
-     *    when that temporary ID was used as a foreign key.
-     *    If the CSV data says (in the metadata again) that it's from a DIFFERENT database,
-     *    we treat all the IDs in the CSV as temporary ID- eg, if the CSV specifies an event with
-     *    ID 1, and the database already has an event with ID 1, we assume that's just a coincidence,
-     *    and insert a new event, and map it's temporary ID of 1 over to its new real ID.
-     *    An important exception are non-auto-increment primary keys. If one entry in the
-     *    CSV file has the same ID as one in the DB, we assume they are meant to be
-     *    the same item, and instead update the item in the DB with that same ID.
-     *    Also note, we remember the mappings permanently. So the 2nd, 3rd, and 10000th
-     *    time you import a CSV from a different site, we remember their mappings, and
-     * will try to update the item in the DB instead of inserting another item (eg
-     * if we previously imported an event with temporary ID 1, and then it got a
-     * real ID of 123, we remember that. So the next time we import an event with
-     * temporary ID, from the same site, we know that it's real ID is 123, and will
-     * update that event, instead of adding a new event).

+	 *    Given an array of data (usually from a CSV import) attempts to save that data to the db.
+	 *    If $model_name ISN'T provided, assumes that this is a 3d array, with toplevel keys being model names,
+	 *    next level being numeric indexes adn each value representing a model object, and the last layer down
+	 *    being keys of model fields and their proposed values.
+	 *    If $model_name IS provided, assumes a 2d array of the bottom two layers previously mentioned.
+	 *    If the CSV data says (in the metadata row) that it's from the SAME database,
+	 *    we treat the IDs in the CSV as the normal IDs, and try to update those records. However, if those
+	 *    IDs DON'T exist in the database, they're treated as temporary IDs,
+	 *    which can used elsewhere to refer to the same object. Once an item
+	 *    with a temporary ID gets inserted, we record its mapping from temporary
+	 *    ID to real ID, and use the real ID in place of the temporary ID
+	 *    when that temporary ID was used as a foreign key.
+	 *    If the CSV data says (in the metadata again) that it's from a DIFFERENT database,
+	 *    we treat all the IDs in the CSV as temporary ID- eg, if the CSV specifies an event with
+	 *    ID 1, and the database already has an event with ID 1, we assume that's just a coincidence,
+	 *    and insert a new event, and map it's temporary ID of 1 over to its new real ID.
+	 *    An important exception are non-auto-increment primary keys. If one entry in the
+	 *    CSV file has the same ID as one in the DB, we assume they are meant to be
+	 *    the same item, and instead update the item in the DB with that same ID.
+	 *    Also note, we remember the mappings permanently. So the 2nd, 3rd, and 10000th
+	 *    time you import a CSV from a different site, we remember their mappings, and
+	 * will try to update the item in the DB instead of inserting another item (eg
+	 * if we previously imported an event with temporary ID 1, and then it got a
+	 * real ID of 123, we remember that. So the next time we import an event with
+	 * temporary ID, from the same site, we know that it's real ID is 123, and will
