TensorCast v0.4.0

Version 0.4 has significant changes:

• Broadcasting options and index ranges are now written @cast @avx A[i,j] := B[i⊗j] (i ∈ 1:3) instead of @cast A[i,j] := B[i⊗j] i:3, axv (using LoopVectorization.jl for the broadcast, and supplying the range of i).
• To return an array without naming it, write an underscore @cast _[i] := ... rather than omitting it entirely.
• Some fairly obscure features have been removed for simplicity: Indexing by an array @cast A[i,k] := B[i,J[k]] and by a range @cast C[i] := f(D[1:3, i]) will no longer work.
• Some dimension checks are inserted by default; previously the option assert did this.
• It uses LazyStack.jl to combine handles slices, simplifying earlier code. This is lazier by default, write @cast A[i,k] := log(B[k][i]) lazy=false (with a new keyword option) to glue into an Array before broadcasting.
• It uses TransmuteDims.jl to handle all permutations & many reshapes. This is lazier by default -- the earlier code sometimes copied to avoid reshaping a PermutedDimsArray. This isn't always faster, though, and can be disabled by lazy=false.

New features in 0.4:

• Indices can appear ouside of indexing: @cast A[i,j] = i+j translates to A .= axes(A,1) .+ axes(A,2)'
• The ternary operator ? : can appear on the right, and will be broadcast correctly.
• All operations should now support OffsetArrays.jl.
• You can repeat by broadcasting over indices not appearing on the right, such as @cast r[i,(k,j)] = m[i,j]
