Added license files
Cleaned up documentation
Bunch of work on rendering process
Set shape back to rectangle, until I can decode the polygon objects in GraphViz
Cleaned up operations a bit; fixed node fill color with a hack; removed attributes objects and replaced with QHash functions in QGraphViz parent object; Removed QGraphVizLabel object as it can be specialized depending on the node or edge rendering
Added level-of-detail for rendering large graphs; added graph view widget; added picture-in-picture; added zoom; added pan
Working on node collapse and zoom widget
Merge branch 'devel' of ssh://aws.threebrooks.com/~/git/qgraphviz into devel
More work toward node collapsing
level of detail; pre-render optimizations; picture-in-picture movements
Fixed path to test files
PIP go-to with double click
Fixed qmake script
Parted project into library and test app; better PIP border painting; better LOD for edges (drawing straight beziers as simple lines) and for nodes
Added node selection
Added support for keyboard control of view
Set Z value for all nodes so they will always be drawn on top of the edges
Worked on keyboard support
Added test files from Greg Lee (LLNL)
Better selection handling and display
