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

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

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

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

Tested

Continued debugging BP1 Writer for a single variable write

Fixed a number of minor things for DataMan engine. The first real-world demo code ran successfully with the AdiosPP framework

Pull request to Jason's branch

Run ./buildDataman.sh see contents for detailed info

see examples/hello/dataman and examples/hello/writer for working
examples

Corrected bug by including cmath in adiosFunctions.cpp

Removed helloWriter.cpp and helloDataMan.cpp, now using
helloDataMan_OOP.cpp and helloWriter_OOP.cpp

DataMan class implemented under include/engine/dataman and
src/engine/dataman

Implemented transport MdtmMan used by DataMan engine under
include/transport and src/transport. This will serve as the basis for
WAN transport

Modified Makefile to include DataMan paths

To do:

Create Format class and assign BP Format to it

Compile and test a Hello DataMan example

Run and tested helloWriter under examples/hello/writer
Fixed Makefile

Added example/hello/dataman with API examples
Changed mpidummy.h due to an error in Titan compilation with g++

This version compiles. 
Tested with 2 write APIs:

under examples/hello/singleBP
helloSingleBP.cpp -> using ADIOS single manager class from ADIOS.h
helloSingleBP.cpp -> using ADIOS objects from ADIOS_OO.h

both generate a .bp file using a POSIX transport

To do:
Test compilation in other platforms/compilers
Add coverage test cases
Add the NULL transport (does nothing)
Work on SingleBP engine to generate bp format
XML config file support (to be defined)
