Displaying mutations on the map

Hi fellow curators,

I have modified the map slightly to show a more readable location (when you hover over a position) and also to underline the positions for which we have mutations.

It would be cool if everyone would take a look at the map at let me know if the underline is not clear enough of an indication.

I experimented with different font colors, but since we are using the Blue color to distinguish exons, changing the color is too confusing.

Thanks!

Keith
