added highlight on mouse pointer passage, does not un-highlight
reimplementing HTML element highlighting using QWebFrame::hitTestContent()
added all files
segmentation fault, heatmap with timer
heatmap and mywebview working with timer, no apparent errors.
Unified design under QMainWindow. Heatmap and MyWebView are inserted separately as properties of the main window. Mouse tracking had propagation problem and it has been solved by tracking the mouse in MyWebView (which is the main widget of the main window) and then sending a signal from MyWebView to QMainWindow. Menus have been added in the main window to allow selection of tracking modes (mouse or OpenGazer) both in HTML element selection and in heatmap.
Forgot to add mainwidget.cpp and mainwidget.h in last commmit
