3rd party static libraries: Integrate Static Frameworks with the CLI Plugins Mechanism

[PanayotCankov]

Subtask of #62

It only seems convenient to ask the users wrap static libraries that go with headers in a framework.

For example in case you have the libMyLibrary.a and a few headers that go with it (like the MagTek library) you can wrap it as:

MyLibrary.framework
├── MyLibrary <- libMyLibrary.a with the "lib" prefix and ".a" extension stripped
└── Headers
    ├── MyLibrary.h <- An umbrella header that eventually includes ClassA.h and ClassB.h
    ├── ClassA.h
    └── ClassB.h

In any case it seems more convenient to use this convention rather than inventing a home made package.json configuration.

So packed frameworks will be usable in nativescript.

Hi,

I created a framework following the structure you mentioned:

MyLibrary.framework
├── MyLibrary <- libMyLibrary.a with the "lib" prefix and ".a" extension stripped
└── Headers
├── MyLibrary.h <- An umbrella header that eventually includes ClassA.h and ClassB.h
├── ClassA.h
└── ClassB.h

But when I was trying to add it by tns library add ios , I got this error:
The bundle at <the path of the framework> does not contain an Info.pllist file.

Could you help me with this? I am trying to use WeChat's ios sdk in NS, however the sdk only provides the header files and the static library file(.a file).
