 This objects defines details for each row if the chosen _type_ of method for buttons and/or rows (defined in _operations/buttons_ and/or in _operations/row_) is *redirect_custom*. The examples very well explains what is needed.
   * *buttons*: is an *object* which has more than one object inside, indexed by a key. This key is the _id_ defined formerly in _operations/buttons/id_. In this case, the id of the button chosen is _"edit"_. redirect_custom method needs a *caption* (a *string*), which defines what the caption of the button should show when the user clicks on that very row, and a *link* (a *string*) which will be the page where the user should be redirected when that very row is selected and the button is clicked.
-  * *row*: is an *object*, which contains only a *link* option, which is a *string* that contains an URL. That string defines where the user should be redirected when clicking on a row.

+  * *row_buttons* is an *object* which has more than one object inside, indexed by a key. This key is just for reference, to make it unique between all the row buttons. The *caption* (a *string*) defines the caption of the button once is appended to the *append_to_column* (another *string*) column of the row it refers to. *append_to_column* must be a valid column _name_ in the _colModel_ array (see _configurations/colModel_). *type* and *parameters* follow the same rules as per the global _buttons_ in _operations_ objects (see _operations/buttons_). Only *redirect_simple* is enabled at the moment.
