Generate source file of definitions from header file

[michelleangela]

Other than genenrating function definition one by one, we need to generate a whole cpp files from the header. i.e. After we finish the declaration of a class or some functions in .h, we can create a .cpp with those definitions there. The extention c/c++ definition generator extenstion implements some functions, but far away from perfect.

It would be great if cpptool adding such a feature.

It'd also be great to be able to separate the definitions in existing header-only libraries to source files. Really appreciate if someone can work on this!

It would also be good to have an option to disable jumping to the .cpp file after generating, as well as not opening the .cpp file in the current split if it is the active file in another split.

@0verEngineer Did/Can you file a feature request for the disable jumping? The not opening the .cpp file in the current split can already be changed by setting editor.revealIfOpen to true.
