Build from one C/C++ header

[VadimGush]

There might be a case when a certain project has one main header file which includes all other header files which are used in the project. And in that case we might want to actually combine this main header with all its dependent headers together.

So basically if we have main.h which includes /utils/utils.h and /other/other.h we want to get the header that will contain the content of main.h, utils.h and other.h in one file.
