1062: docstring ensure signature code formatting r=CarloLucibello a=visr
by using a four space indent instead of two
Fixes issues seen here:
Where the type signature has no code formatting, and a code block is introduced that throws off the rest of the formatting.

1023: Feature: Added Boston Housing Dataset r=CarloLucibello a=pranjaldatta
[Boston Housing Dataset](https://archive.ics.uci.edu/ml/machine-learning-databases/housing/) is one of the most common datasets that are used by beginners. It is as popular as other datasets like Iris etc. Hence, it feels only natural that this dataset is a part of Flux.
Added src/data/housing.jl: code for downloading and loading the dataset
Edited src/data/Data.jl: To include and export housing.jl
Edited test/data.jl: Added test for the dataset.
*All tests in test/data.jl are passing*

960: Added utility function outdims to compute output dimensions of a layer r=dhairyagandhi96 a=darsnack
Based on Slack chatter, I added a utility function, `outdims`, that computes the output dimensions for given input dimensions.
Example
```julia
layer = Conv((3, 3), 3 => 16)
outdims(layer, (10, 10)) # returns (8, 8)
```

898: Fix problem in crossentropy breaking GPU compilation r=MikeInnes a=kshyatt
Trying to run this simple example
```
using Flux, CuArrays
using Flux: crossentropy
model = Chain(
Dense(728, 128, σ),
LSTM(128, 256),
LSTM(256, 128),
Dense(128, 10),
softmax) |> gpu
data = [rand(728) for i in 1:100];
out = [rand(10) for i in 1:100];
loss(x, y) = crossentropy(model(x), y);
Flux.train!(loss, params(model), zip(gpu.(data), gpu.(out)), ADAM())
```
Old version of `crossentropy`:
```
ERROR: GPU compilation of #23(CuArrays.CuKernelState, CUDAnative.CuDeviceArray{Float32,1,CUDAnative.AS.Global}, Base.Broadcast.Broadcasted{Nothing,Tuple{Base.OneTo{Int64}},typeof(*),Tuple{Base.Broadcast.Extruded{Array{Float32,1},Tuple{Bool},Tuple{Int64}},Base.Broadcast.Broadcasted{Base.Broadcast.ArrayStyle{CuArray},Nothing,typeof(conj),Tuple{Base.Broadcast.Extruded{CUDAnative.CuDeviceArray{Float32,1,CUDAnative.AS.Global},Tuple{Bool},Tuple{Int64}}}}}}) failed
KernelError: passing and using non-bitstype argument
Argument 4 to your kernel function is of type Base.Broadcast.Broadcasted{Nothing,Tuple{Base.OneTo{Int64}},typeof(*),Tuple{Base.Broadcast.Extruded{Array{Float32,1},Tuple{Bool},Tuple{Int64}},Base.Broadcast.Broadcasted{Base.Broadcast.ArrayStyle{CuArray},Nothing,typeof(conj),Tuple{Base.Broadcast.Extruded{CUDAnative.CuDeviceArray{Float32,1,CUDAnative.AS.Global},Tuple{Bool},Tuple{Int64}}}}}}.
That type is not isbits, and such arguments are only allowed when they are unused by the kernel. .args is of type Tuple{Base.Broadcast.Extruded{Array{Float32,1},Tuple{Bool},Tuple{Int64}},Base.Broadcast.Broadcasted{Base.Broadcast.ArrayStyle{CuArray},Nothing,typeof(conj),Tuple{Base.Broadcast.Extruded{CUDAnative.CuDeviceArray{Float32,1,CUDAnative.AS.Global},Tuple{Bool},Tuple{Int64}}}}} which is not isbits.
.1 is of type Base.Broadcast.Extruded{Array{Float32,1},Tuple{Bool},Tuple{Int64}} which is not isbits.
.x is of type Array{Float32,1} which is not isbits.
