Interval arithmetic

[ghost]

In the Readme, regarding PDEs:
d=Interval()^2.
In Julia 0.3.0, ApproxFun 0.0.3, This raises an error,
ERROR: '*' has no method matching *(::Interval{Float64}, ::Interval{Float64}) in power_by_squaring at intfuncs.jl:56 in ^ at intfuncs.jl:86
And somewhat hobbles the PDE solving efforts. Indeed, it appears no arithmetic is defined for the Interval type. Is there an implicit dependency that one must build?

Hi Chris,

The readme is updated for the latest master.  Try 

    d=Interval()⊗Interval()
