Provide better HTML output from the "report html" command

Maybe a table more like the input file, but this time with the internal nodes as columns as well? The individual cells could show the observed/inferred count and the change from that nodes ancestral state. For example, if I make up an input family: Family ID Human Chimp Gorilla 1 3 1 0 The output could be a table like this:

Tree ((Human,Chimp)<1>,Gorilla)<2>

Family ID Human Chimp Gorilla <1> <2> 1 3 / +2 1 / +0 0 / -1 1 / +0 1 / NA Another column could be added for the family p-value, and we could add a symbol next to the changes (ie +2*) or make them bold if they are rapidly evolving (if the lineage p-value < 0.01). It would also be useful to have an image of the tree with the internal nodes labeled somewhere visible.
