\brief Sort data in a \l SortFilterProxyModel based on ordering of the
locale.
StringSorter allows the user to sort the data according to the role name
as configured in the source model. StringSorter compares strings according
to a localized collation algorithm.
The StringSorter can be configured in the sort filter proxy model as below,
\qml
SortFilterProxyModel {
model: sourceModel
sorters: [
StringSorter { roleName: "name" }
]
}
\endqml
