/*
Select is a collection of API methods, event handlers, event emitters and
buttons (for the `Buttons` extension) for DataTables. It provides the following
features, with an overview of how they are implemented:
## Selection of rows, columns and cells. Whether an item is selected or not is
stored in:
* rows: a `_select_selected` property which contains a boolean value of the
DataTables' `aoData` object for each row
* columns: a `_select_selected` property which contains a boolean value of the
DataTables' `aoColumns` object for each column
* cells: a `_selected_cells` property which contains an array of boolean values
of the `aoData` object for each row. The array is the same length as the
columns array, with each element of it representing a cell.
This method of using boolean flags allows Select to operate when nodes have not
been created for rows / cells (DataTables' defer rendering feature).
## API methods
A range of API methods are available for triggering selection and de-selection
of rows. Methods are also available to configure the selection events that can
be triggered by an end user (such as which items are to be selected). To a large
extent, these of API methods *is* Select. It is basically a collection of helper
functions that can be used to select items in a DataTable.
Configuration of select is held in the object `_select` which is attached to the
DataTables settings object on initialisation. Select being available on a table
is not optional when Select is loaded, but its default is for selection only to
be available via the API - so the end user wouldn't be able to select rows
without additional configuration.
The `_select` object contains the following properties:
```
{
items:string - Can be `rows`, `columns` or `cells`. Defines what item
will be selected if the user is allowed to activate row
selection using the mouse.
style:string - Can be `none`, `single`, `multi` or `os`. Defines the
interaction style when selecting items
blurable:boolean - If row selection can be cleared by clicking outside of
the table
info:boolean - If the selection summary should be shown in the table
information elements
}
```
In addition to the API methods, Select also extends the DataTables selector
options for rows, columns and cells adding a `selected` option to the selector
options object, allowing the developer to select only selected items or
unselected items.
## Mouse selection of items
Clicking on items can be used to select items. This is done by a simple event
handler that will select the items using the API methods.
