a C++ version qudt4dt sample lib

[imjjs]

To create a sample library which can make the sample code exec.

The structure looks good and the sample code runs on Windows under Visual Studio. The API looks pretty good from a user perspective, and I like the style of code that the user can write with it.

I have two questions about the abstractions chosen:

• What does it mean to cast "b" as a ModelicaQuantity?
• Why do we instantiate ModelicaQuantity using the unit URL, instead of a defined type as done with qudt4dt::inch and qudt4dt::meter?

What part of the API are you currently working on?

[imjjs]

The default way to create a ModelicaQuantity is passing a QudtQuantity, however, user can also use a URL to create a abritary Quantity (both qudt and modelica).

And the next step is to implement the database accessing part.

[imjjs]

1. using the static data structure for each unit field
2. creating the abstract layer for the database accessing part

[imjjs]

Done the database accessing part with libcurl. The next step is to parse the result with libjsoncpp.

[imjjs]

reorganizing the project dir, and adding CMAKE build system

This issue looks good! I will merge it to master.

The only thing we are waiting for before closing the issue is to see if the small change to get_dependencies.py works on both Windows and Linux.
