Change Backends

PowerGraphics.jl relies on Plots.jl to enable plotting via different backends. See the Plots.jl section on backends for more details. Currently, two backends are supported in PowerGraphics.jl:

• GR (default): creates static plots — run the gr() command to load
• PlotlyJS: creates interactive plots — run the plotlyjs() command to load

If you run neither command, PowerGraphics.jl will default to using GR.
