/**
 * Footer block used within [models-table](Components.ModelsTable.html).
 *
 * Usage example:
 *
 * ```hbs
 * <ModelsTable @data={{data}} @columns={{columns}} as |MT|>
 *   <MT.Footer />
 *   {{! .... }}
 * </ModelsTable>
 * ```
 *
 * Usage example with a block context:
 *
 * ```hbs
 * <ModelsTable @data={{data}} @columns={{columns}} as |MT|>
 *   <MT.Footer as |Footer|>
 *     <Footer.Summary />
 *     <Footer.PageSizeSelect />
 *     {{#if useNumericPagination}}
 *       <Footer.PaginationNumeric />
 *     {{else}}
 *       <Footer.PaginationSimple />
 *     {{/if}}
 *   </MT.Footer>
 * </ModelsTable>
 * ```
 *
 * ModelsTableFooter yields references to the following contextual components:
 *
 * * [models-table/summary](Components.ModelsTableSummary.html) - component with summary info about table data. It also contains button to clear all filters applied to the table
 * * [models-table/size-select](Components.ModelsTableSizeSelect.html) - component with a page sizes dropdown. It allows to select number if records shown on page
 * * [models-table/pagination-numeric](Components.ModelsTablePaginationNumeric.html) - component with a table navigation. It allows to move to the page by its number
 * * [models-table/pagination-simple](Components.ModelsTablePaginationSimple.html) - component with a table navigation. It allows to move to the first, last, prev and next pages (this four buttons are shown always)
 *
 * Check own docs for each component to get detailed info.
