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

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

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

Keep only std::map<std::string, std::string> initializer list.
Corrected examples. 

Initial implementation of XML running with helloBPWriter example
Corrected bug in ADIOS.cpp when detecting IO in ConfigFile

m_Name must a string object not a const reference. 

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

To do: 
Debug hello_datamanWriter non-MPI version

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

Some code for joined array reading in adios1 engine, incomplete. Rather should support it in adios1 itself.
Committed only to have a working Write/Read API so that we can have examples with global arrays finalized.

in Variable.h and VariableBase.h

- Added examples/groupless/multistep writer example to the build
- Added ADIOS1 reader but it does not work yet
- Added heat transfer example reader

Updated adiosFunctions.cpp
Corrected warnings, missing return and signature in ResizeBuffer

Created public function ResizeBuffer in BP1Writer

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
