Adjustments to setup.py and README for torch Sobol (#20)

Summary:
Pull Request resolved: facebook/Ax#20

Pull Request resolved: #55

Using the torch native SobolEngine makes things a lot simpler for botorch.
ax still uses the cython SobolEngine for a lot of things outside torch land.

-BoTorch is a library for Bayesian Optimization in PyTorch.
+BoTorch is a library for Bayesian Optimization built on PyTorch.
 
-It is currently an alpha version under active development - be warned!
+*BoTorch is currently in alpha and under active development - be warned*!
 
 
-## Installation
+### Why BoTorch
+BoTorch
+* Provides a modular and easily extensible interface for composing Bayesian
+  optimization primitives, including probabilistic models, acquisition functions,
+  and optimizers.
+* Harnesses the power of PyTorch, including auto-differentiation, native support
+  for highly parallelized modern hardware (e.g. GPUs) using device-agnostic code,
+  and a dynamic computation graph.
+* Supports Monte Carlo-based acquisition functions via the
+  [reparameterization trick](https://arxiv.org/abs/1312.6114), which makes it
+  straightforward to implement new ideas without having to impose restrictive
+  assumptions about the underlying model.
+* Enables seamless integration with deep and/or convolutional architectures in PyTorch.
+* Has first-class support for state-of-the art probabilistic models in
+  [GPyTorch](http://www.gpytorch.ai/), including support for multi-task Gaussian
+  Processes (GPs) deep kernel learning, deep GPs, and approximate inference.
 
-##### Setup Requirements (TODO: Remove once we can use torch Sobol)
 
-The following are required to run the setup:
+### Target Audience
 
-- Python >= 3.6
-- numpy
-- cython
+The primary audience for hands-on use of BoTorch are researchers and
+sophisticated practitioners in Bayesian Optimization and AI.
+
+We recommend using BoTorch as a low-level API for implementing new algorithms
+for [Ax](https://github.com/facebook/Ax). Ax has been designed to be
+an easy-to-use platform for end-users, which at the same time is flexible enough
+for Bayesian Optimization researchers to plug into for handling of feature
+transformations, (meta-)data management, storage, etc.
 
+We recommend that end-users who are not actively doing research on Bayesian
+Optimization simply use Ax.
 
-##### Installation Requirements
 
-- PyTorch >= 1.0.1
-- gpytorch >= 0.3.0
+## Installation
+
+#### Installation Requirements
+
+- Python >= 3.6
+- PyTorch nightly (**TODO:** peg to PyTorch 1.1 once released)
+- gpytorch >= 0.3.1 (**TODO:** peg to GPyTorch 0.3.2 once released)
 - scipy
 
-**Important:**
-You will want to have you PyTorch build link against **MKL** (the non-optimized
-version of botorch can be up to an order of magnitude slower). Setting this up
-manually can be tricky - to make sure this works please use the Anaconda
-installation instructions on https://pytorch.org/.
+**Important note for MacOS users:**
+* You will want to make sure your PyTorch build is linked against MKL (the

+  some settings). Setting this up manually on MacOS can be tricky - to ensure
+  this works properly please follow the
+  [PyTorch installation instructions](https://pytorch.org/get-started/locally/).
+* If you need CUDA on MacOS, you will need to build PyTorch from source. Please
+  consult the PyTorch installation instructions above.
 
 
-### Install botorch
+#### Installing BoTorch
 
-To run the botorch setup, you'll need cython (**TODO:** Remove)
+The latest release of BoTorch is easily installed using either pip or conda:
 ```bash
-pip install cython
+pip install botorch
 ```
 
-We recommend installing botorch using pip via ssh:
+**TODO: Conda install**
+
+
+If you'd like to try our bleeding edge features (and don't mind running into an
+occasional bug here or there), you can install the latest master from GitHub
+(this will also require installing the current GPyTorch master)::
+```bash
+pip install git+https://github.com/cornellius-gp/gpytorch.git
+pip install git+https://github.com/facebookexternal/botorch.git
+```
+
+
+#### Installing BoTorch from the private repo **TODO: REMOVE**
