Use of triangular dispatch invalid

[IainNZ]

This definition for ARD seems to invalid in Julia 0.4, and I think should be invalid in 0.3 too but might not be due to a change.

MLKernels.jl/src/kernels.jl

Line 62 in c1532ce

immutable ARD{T<:FloatingPoint,K<:StandardKernel{T}} <: SimpleKernel{T}

immutable ARD{T<:FloatingPoint,K<:StandardKernel{T}} <: SimpleKernel{T}

In particular the K part. I can't find exactly where it was changed, but here is related discussion

JuliaLang/julia#6620
JuliaLang/julia#3766
JuliaLang/julia#8974 (comment)

I'm a bit confused on how this all works internally, might be worth posting on julia-users if you want to get it working on 0.4 at some point.

Fixed.
