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

* Support PutDeferred() in ADIOS1 writer

* added PerformPuts() to ADIOS1Writer

* refactor toolkit/interop/adios1/ADIOS1Common in preparation for having separate Write and Read classes

* Working towards ADIOS1 Reader. Changes the Engine.BeginStep() signature for all engines.

examples/hello/bpTimeWriter/helloBPWriteStep.cpp

examples/hello/bpWriter/hellBPPutDeferred.cpp

BPWrite_c -> ctypes
XMLConfigTest.TwoIOs -> Test BP Writer 1

Passed ctest (MPI and nonMPI) excluding ADIOS1 engine, and Python bindings
HDF5, C bindings and C++ tests working
Introduced BeginStep EndStep functions
Renamed IO GetVariable/Attribute to InquireVariable/Attribute

Getting and defining available Variables at Open
Storing Variable position in Metadata, added to VariableBase
mpidummy: Added support for MPI_Reduce, MPI_Gatherv
Added utils and BPLS

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

Added test for generating profiling.json
Fixed inclusion for NLohmannJson json.hpp in Test
Tested resulting profiling.json on R (jsonlite), Python (json)
and C++ (json for modern C++)

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

Adapted to the new code structure
BP1Writer is a self-contained class that can be reused across Engines
BP1Writer allows for threaded copies for large payloads

To do:
Data Buffer memory management strategy

Move adiosTemplates.h to adiosTemplate.inc

Removed elements that are not used

Using {} syntax for direct initialization of reference types in constructor
member initialization lists is broken on some compilers, even though it's valid
C++11 code.  Use () to ensure correctness.

added: 
./packages/format/bp1
./packages/profiling/iochrono
./packages/wan/dataman (for DataMan integration in ADIOS)

Will merge into groupless branch

Need to verify metadata footer

Will need a new branch to implement variable merging as it implies
changing the BP1.h structs

Updated README.md files

Python bindings now working with PyBind11

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

Changed FD and FP to FileDescriptor and FilePointer, respectively.

Added Profiler class based on chronos header for high resolution time
information in buffering and transport open, write, close

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)

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
