 * Implements a styling API for {@link FlexGrid} controls.
 *
 * To style cells in a {@link FlexGrid} control, create an instance
 * of the {@link FlexGridStyle} and pass the grid as a parameter to the
 * constructor. For example:
 *
 * ```typescript
 * import { FlexGrid } from 'wijmo/wijmo.grid';
 * import { FlexGridStyle } from 'wijmo/wijmo.grid.style';
 * let theGrid = new FlexGrid('#theGrid'); // create the grid
 * let flexGridStyle = new FlexGridStyle(theGrid); // create an object of FlexGridStyle
 * ```
 *
 * The {@link FlexGridStyle} class depends on the **wijmo.grid** module.
 *
 * The example below shows how you can use {@link FlexGridStyle} to add/remove
 * styles on {@link FlexGrid} control:
 *
 * {@sample Grid/Styling/StyleAPI/purejs Example}
