// .NAME QFilterTreeProxyModel - An implementation of a QSortFilterProxyModel
// tailored for hierarchical models.
//
// .SECTION Description
// An implementation of a QSortFilterProxyModel tailored for hierarchical
// models. It allows you to filter the model based on the content in a
// certain column of a certain level in the tree. Indices above that level
// in the tree are retained. Indices below the level are kept if their
// ancestor at the tree level is kept.
