If IO object to be used.
InquireIO returns nullptr if DeclareIO not called.
Two calls to DeclareIO with the same name will throw an exception

Resolving long ambiguity
Correcting APPLE MACROS

Need to add examples and tests
Fixed some bugs in Attribute Read

Working on Fortran examples
Testing Row Major Reader
Debugging parallel read
Changed file open function
Added initial tests 1D and 2D

Attempting to solve HDF5 failed tests on summitdev

Remove cdash warnings for unused variables, type cast (including HDF5
char vs. int8) and virtual functions overloads.

Debug hello_bpWriter

Windows address access
Example reader file name

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

Continue refactoring IO, ADIOS classes

Changed m_Transports from vector to map, needed by subfile manager

BP3 Deserialization:
Getting subfile seeks and intersection info
Set host language in bindings for row-major and zero-index info

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 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

Refactored IO, Variable class due to common functionality

Wrapper classes CompressBZip2 and CompressZfp implemented
Under transform/compress and adding examples and tests
Added/Modified cmake files
Makign changes to cmake from PR review

To do:
Add more tests

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

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

If file doesn't exist, continue with run
Fixed bug if space before and after "=" in: <tag attribute1= "value1">

To do: need to discuss policy for config files, still experimental
