Remove standalone ADIOS2/HDF5 heat transfer codes and use the one-and-only ADIOS2 version of the code with all available engines.

Updated heatTransfer write part: common handling filename argument; uses PutDeferred and skips PerformPuts

Now passing numpy array in DefineVariable
autopep8 syntax errors

Refactored heat transfer example. A config file is now command line argument. Reader's decomposition is also command line argument.

    read_fileonly/ contains the file reader examples,
    read/ contains the streaming version,
    writer and reader is using heat.xml config file from the root directory

Need to test, right now not working

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
