fixed a few problems of DataMan/ZeroMQ, and added a simple Transport::Read() API to make the hello world workflow working again

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

Implemented basic buffer reading functionality
Added threading for bp serialization/deserialization
Refactored MPI functionality
Engine is now a reference
Initial Read API

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

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

Tested

added: 
./packages/format/bp1
./packages/profiling/iochrono
./packages/wan/dataman (for DataMan integration in ADIOS)

Continued debugging BP1 Writer for a single variable write

Pull request to Jason's branch

Other DataMan library dependencies must be in LD_LIBRARY_PATH

Modified Makefile.libs and Makefiles in ./examples/hello/datamanReader
and ./examples/hello/datamanWriter

Need to set DATAMAN_LOC in those makefiles for local DataMan
installation.

Need to set DATAMAN_LOCATION in buildDataMan.sh for local DataMan
installation.

Run ./buildDataman.sh see contents for detailed info
