Title: lineWithFocusChart: add tickFormat support a la lineWithFocus code

as a result of a d3 ML question "nvd3.js: Mouse over line doesn't show tooltip"

gist http://bl.ocks.org/3036633 --> gist http://bl.ocks.org/3190391

added .xTickFormat() and .yTickFormat() API methods to make chart axis public I/F as capable as that of lineWithFocus.js - from which this code was ripped and then adjusted to compensate for the slightly different way the 2nd x and y axis are named internally.
