Detailed Description

QHeaderView that supports showing multiple sections as one.

cvMultiColumnHeaderView extends QHeaderView to support showing multiple adjacent sections as a single section. This is useful for showing vector quantities, for example. Instead of each component taking up header space and making it confusing to understand that the various sections are part of the same vector, cvMultiColumnHeaderView can show all those sections under a single banner. It still supports resizing individual sections thus does not inhibit usability.

cvMultiColumnHeaderView simply combines adjacent sections with same (non-empty) QString value for Qt::DisplayRole. This is done by overriding QHeaderView::paintSection and custom painting such sections spanning multiple sections.
