Sorting by size or by case

sortAbsolute sorts numbers by their size whatever the sign, and sortCaseSensitive sorts upper and lower case and accents apart.

createGrid(el, {
  columns: [
    { field: 'change', type: 'number', sortAbsolute: true },   // 2, -5, 10, -50 (by size)
    { field: 'code' },
  ],
  data,
  sortCaseSensitive: true,                                     // a, B, b
});

Option	Without	With
sortAbsolute (column)	-50, -5, 2, 10	2, -5, 10, -50
sortCaseSensitive (grid)	a, b, B (or b, B: case ignored)	a, B, b

sortCaseSensitive puts capitals first when two values differ only in case, and also sorts accented letters apart (é after e). It affects grouping order and set-filter lists too.
Numbers inside text still sort as numbers (item 2 before item 10).
For anything else, give the column a comparator(a, b, rowA, rowB).
