Deactiveted ADIOS1 Attribute test
Solved clang-format format and camelCase issues

Implemented basic buffer reading functionality
Added threading for bp serialization/deserialization
Refactored MPI functionality
Engine is now a reference
Initial Read API

Bugs: 1) Missing binary mode in FilePointer fopen and FStream ofstream
transports
      2) Replacing reinterpret_cast of size_t to uint_64, not the same
on Windows 64-bit

Removed some warnings generated by Visual Studio

Added static_cast for type conversions

Refactor XML reader to restore original check on single engine
conditions and eliminate warnings. Test added.

Allow ctime and fopen "not secure" warnings: now using binary fstream as
default file IO library on Windows

Checking std::ios_base::failure exceptions
IOChrono is off by default, each owner turns it on explicitly
Modified FileDescriptor and FilePointer destructors
Added Tests BPWriteRead for stdio and fstream
Removed IO AddTransport with vector (shoud have been there?) to enable
AddTransport in Tests

* Added examples for variables

* fix more example code

* make Open explicit in ADIOS1 toolkit. Fix handling open mode

* fix OpenModeToString() to serve adios 1 API's needs as well

* fix basic examples after code refactoring

* fix nompi build for basic examples

* fix nompi build

bool flag checks are implicit
Removed single letter enums in ADIOSTypes.h
All enums are enum class in ADIOSTypes.h using CamelCase
ADIOS uses delegating constructor
Using return type of emplace for IO (in ADIOS) and Variable (in IO)
Removed all base class include from inl template file

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

Fix hello examples with new DefineVariable() syntax, for BP, timeBP and ADIOS1. Missing HDF5 and DataMan

Will merge into groupless branch

Single variable example works. Moving on to time aggregation example.

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

Tests with bpls indicate that variable payloads are recognized

Renamed BPWriter engine to BPFileWriter

Changed WriteVariableIndex function in BP1Writer to only include a
capsule::STLVector as buffers, other capsules will need to get it from
this heap buffer.

To do:
add profiling info (time)

Now printing last variable values with bpls. 

Need to fix so payload offset is set for all variables correctly. 

Replaced vectors with map containers for Variables to avoid iterator
invalidation when adding element to a container. 

Metadata is correctly interpreted by ADIOS 1.0 bpls

To do:
Need to debug values from bpls -d option

Continued debugging BP1 Writer for a single variable write

examples/hello/bpWriter working

To do:

BPReader examples and BP1Reader class

Added BP1Writer pgindex and metadata functionality. Need to hook it with
BPWriter engine 

Added complex support in ADIOS class and DataMan engine and example for
DataManWriter

Testing

see examples/hello/dataman and examples/hello/writer for working
