Start of refactor of LineGraph

Still contains a lot of code that has just been copied from the current implementation
Merge remote-tracking branch 'refs/remotes/upstream/master' into widget-refactor

Conflicts resolved:
	lineGraphTests.html
Mostly cleaned up and changed formatting in widget-base

Changed { placement to my preferred style to make it easier for me to read.
Merge remote-tracking branch 'refs/remotes/upstream/master' into widget-refactor
more formatting and changes as I gain understanding of the Axes object.
Preliminary refactor of LineGraph now draws a line graph

LineGraph itself has barely been touched. Most work is still progressing on
the Axes class.
Preliminary latest changes to rework so multiple graphs can be added to a single svg container.
oops missed these changes
Merge branch 'refs/heads/master' into widget-refactor
Remove Mac .DS_Store file
Merge remote-tracking branch 'refs/remotes/origin/master' into widget-refactor
New design, using cntr.append and widget.draw for LineGraph is drawing something
More refactoring of Axes, removed Axes.innerWid .innerHt, used local vars may need to add back.

Started trying to refactor out an individual Axis, need to read up on javascript inheritance.

Merge remote-tracking branch 'refs/remotes/upstream/master' into widget-refactor
More work on refactoring Axes into a base Axis class w/ derived LinearAxis, ... classes

Used some of the google closure library to do inheritance. After reading about the myriad
ways people are setting up javascript inheritance and reading what was said here:
http://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml#Multi-level_prototype_hierarchies

I decided to use google's closure library.
Continue w/ the basic refactor using the append method on the svg container and the draw method on the widget (in this initial case LineGraph)
Update the version of d3 v3 in the js folder
