signed char needed by int8_t in C bindings
Added tests

Added portable PathSeparator
Fixed format for bp file name

Added working example examples/hello/bpWriter/helloBPWriter.c
Changed Engine signature to resolve Write void* at runtime (required by
C bindings).

To do:
CMake infrastructure
Testing

Restoring std:: for cstdio functions
Removing warnings explicitly with pragmas

Removed ADIOS copy constructor explicitly, as it wasn't allowed by clang
compiler in testing/xml/TestXMLConfig.cpp

Using more portable preprocessor definitions to avoid warning on Windows
for ctime and fopen

Introduced std::throw_with_nested for bad_alloc in STLVector Capsule

Removed std:: in C function calls to avoid confusion with actual C++
only calls

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

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++)

Missing file_index characteristic in BP1Writer metadata

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

Replace std::copy with std::memcpy in std::thread
Added threads to profiling.log
Limiting the use of threads

TO DO: large scale runs to enforce threads policy

unsigned int checking if < 0
Adding intermediate int verbosity for string conversion stoi

Added example bpFlushWriter (incomplete).

To do:
Memory buffer reallocation strategy

To do: 
Debug hello_datamanWriter non-MPI version

* 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

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

* fix more example code

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

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
