 * @howToUse "Using wider items"
 * ```html
 * <cart-showcase [items]="items" [aspectRatio]="'2:1'">
 * </cart-showcase>
 * ```
 *
 * @howToUse "Using four columns in all screen sizes bigger than 768px"
 * ```html
 * <cart-showcase [items]="items" [mCols]="4" [lCols]="4">
 * </cart-showcase>
 * ```
 *
 * @howToUse "Using a different item component"
 * ```html
 * <!-- my-component.html -->
 * <cart-showcase [items]="items" [itemComponent]="itemComponent">
 * </cart-showcase>
 * ```
 * ```typescript
 * // my-component.ts
 * export class MyComponent {
 *   itemComponent = MyCustomItemComponent;
 * }
 *
 * // my-custom-item-component.ts
 * @Component({
 *  selector: 'my-custom-item-component',
 *  template: '<div class="item-class">{{item.getName()}}</div>'
 * })
 * export class MyCustomItemComponent implements ShowcaseItem  {
 *   item: CartItem;
 * }
 *
 * // app.module.ts
 * @NgModule({
 *   // .....
 *   entryComponents: [MyCustomItemComponent],
 * })
 * export class AppModule {
 * }
 * ```
 *
 * @note {warning} If you change the `[columns]` input you must also change the sass variable that controls the component grid and
 * vice-versa. A similar procedure is required to create aspect ratios with values greater than four eg: `'1:5'`. Check the styling guide
 * for more information.
 *
 * @note {danger} The aspect ratio is the width/height proportion of the items therefore a ratio of `'2:2'` is equivalent to `'1:1'`.
 * Redundant ratios like these are removed from the source so don't try to use them.
