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

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

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

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

- 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

helloBPWriter and timeBPWriter
