Remove hard coded Float64

There should be nothing in the algorithms that depend on the parameters being Float64: BigFloat should in principle be allowed, though I suppose there may be assumptions on eps(T) for...

CLArray{Float32,2}(10,10) throws ambiguity error

2

```julia julia> CLArray{Float32,2}(10,10) ERROR: MethodError: CLArrays.CLArray{Float32,2}(::Int64, ::Int64) is ambiguous. Candidates: (::Type{CLArrays.CLArray{T,N}})(size, ptr) where {T, N} in CLArrays at /Users/solver/.julia/v0.6/CLArrays/src/array.jl:12 (T::Type{#s9} where #s9

I'm not sure if this should work, but nevertheless it throws an error: ```julia julia> A = CLArray{Float32}(randn(100,100)); julia> b = CLArray{Float32}(randn(10)); julia> view(A,1:10,1:10)*b ERROR: conversion to pointer not defined...

Should the convenience constructor be `zero(CLArray{Float32}, n, n)` instead of `zeros`?

13

I'm in the process of replicating the `zeros` and `eye` convenience constructors in BandedMatrices.jl and other packages, see https://github.com/JuliaMatrices/BandedMatrices.jl/issues/42 Personally, the semantics of `zeros(CLArray{Float32},n,n)` seems wrong as it looks like...

Femtocleaner not running on SingularIntegralEquations.jl

I tried running Femtocleaner (both by creating an Issue and by bumping REQUIRE) on https://github.com/JuliaApproximation/SingularIntegralEquations.jl and I didn't receive a PR.

Clean up Hilbert v SingularIntegral

`SingularIntegral(S,0)` is _really_ different than `SingularIntegral(S,1)`: it's real valued, is not `(x-z)^0`, etc. I think `LogKernel` and `SingularIntegral` should be different types.

2F1 sometimes errors due to Gamma function:

```julia n = 5; a ,b = 0.1, 0.2 _₂F₁(-n,n+a+b+1,a+1,z+eps()*im) ```

logkernel sometimes throws domain error due to `acos`
