(Squashing this commit but going to leave the full log here, unlike the way I usually do things)

* Incremental work on compatibility with system requirements

* Lower cmake version requirement so we can work with CentOS 7.4

* Force TBB disabled if CMake is too old to build it (for CentOS)

* Build LLVM OpenMP as external project

* Tweak LLVM build options

* Minor comment edit in cmake scripts

* Workaround (fix?) for codegen crashes on CentOS

* Add some header paths for CentOS to resource_generator; temporary(?) tweak to ignore nonexistent paths

* Remove CMake compatibility figleaf since LLVM will require 3.1+ anyway

* Fix the TBB-enable flag to default to on

* Remove hard-coded choice of clang as tbb compiler

* ln -s -> ln -sf in command to create link for OpenMP source dir

* Make OpenMP build so it doesn't require symlink

* Tweak CI cmake options to use prebuilt LLVM

* Remove debug messages

* Rework defaulting behavior for LLVM_TARBALL_URL and LLVM_SHA1_HASH

* Remove warning message for unavailable header file directories

Clean up

* Changes from review

* Add an overivew.

* Intro for building graphs.

* Refactor docs so that Doxygen and Sphinx are integrated (Sphinx depends on Doxygen with the docstrings stuff)

Still need to resolve a lingering assumption that the build dir is contained in private-ngraph-cpp. It's proving to be surprisingly tricky.

* Added the TensorFlow XLA build information and example of how to run MNIST MLP with TF/nGraph

* Updated TF integration guide for clarity. Added files from cyphers-amazon branch. Add minor changes to sphinx-doxy to test apis

* Small revision of overview and add graphic from arXiv paper

* WIP more editing, picking up from where I left off last week

* Fix garbled sentence edit

* WIP Edit for readability and such

* Missed merge conflict

* Add something on functions, don't forward-reference parameters

* What we have so far into a PR for review

* Need file for cmake

* Missing header
