Verified MPI and sequencial version

Removed IO Open that takes a new communicator (didn't work)

* Add initial python support to CMake build

* pybind11 2017-04-07 (1df91d36)

Code extracted from:

    https://github.com/pybind/pybind11.git

at commit 1df91d36cfa997c8987889234304ea5e37cc3e68 (v2.1.1).

* Build python bindings with cmake

* Adjust for adios2py -> adios2 module name

Applied autopep8 from python-pep8 for flake8 formatting in py

Issues:
Linking with Python 3.5 not working as-is with PyBind11
Passing a new communicator in IO Open fails (mpi4py?)

To do:
Add more test cases from other engines

To do:
Implement overloaded and default-argument class functions

Python bindings running but not printing values with bpls. Min and Max
captured correctly.

IO SetParameters and AddTransport will accept vector and map

Variable.cpp and Variable.tcc for complete separation of core components
in the public include

1 Now IO (replaced Method) and is the factory for Variables and Engines
2 Reduced core components to user-public objects only
3 Moved and reorganized all helper functions to helper directory
4 Engines are now lightweight (except for ADIOS1Reader WIP) using MACRO
5 HF5Common and ADIOS1Common (except for Readers WIP) are now part of the toolkit so they can be reused by Engines
6 TransportMan is a new layer for transport management (file is default)
7 DataMan will be implemented under toolkit/transportman/dataman
8 Template separation (tcc and inl) applied all over the code
9 Improved Doxygen documentation

Runtime Issues:
DataMan library compilation (cacheman)
ADIOS1 Warning
TestADIOSInterfaceWrite catches exceptions

Now file.bp/profiling.log is generating capturing I/O profile info

Updated README.md files

Python bindings now working with PyBind11

DefineVariable)

Adding Variable<void> map container in ADIOS for unknown variable types
(until Write). This is required in Python.

Added EnginePy as a thin manager wrapper to adios::Engine (member of
EnginePy)

Write accepts numpy arrays (ndarray) seamlessly

Write Outputs Verified with ADIOS 1.0 bpls

To do:
Advance

Moved CheckBufferAllocation to functions/adiosFunctions.h to make it
available to all engines

Added MethodPy in Python bindings, SetParameters and AddTransports use
raw functions to accept any number of arguments in the form of a
dictionary. Tested with test_hello.py

Started implementation of bindings/python using boost::python
Modified Makefile to allow for dynamic library compilation

To do:
Work on time aggregation
