/**
 * Header Cell definition for the pbl-ngrid.
 * Captures the template of a column's data row header cell as well as header cell-specific properties.
 *
 * `pblNgridHeaderCellDef` does the same thing that `matHeaderCellDef` and `cdkHeaderCellDef` do with one difference,
 * `pblNgridHeaderCellDef` is independent and does not require a column definition parent, instead it accept the ID of
 * the header cell.
 *
 * NOTE: Defining '*' as id will declare the header cell template as default, replacing the table's default header cell template.
 *
 * Make sure you set the proper id of the property you want to override.
 * When the `id` is set explicitly in the table column definition, this is not a problem but when if it's not set
 * the table generates a unique id based on a logic. If `name` is set the name is used, if no name is set
 * the `prop` is used (full with dot notation).
