Is your feature request related to a problem? Please describe.
I would like to extract the complete control flow graph (CFG) of an entire project, including inter-procedural information, using Joern. However, there seems to be no straightforward way to achieve this, and the current documentation lacks detailed guidance. This limitation makes it challenging to analyze projects with complex inter-procedural dependencies efficiently.

Describe the solution you'd like
I would like Joern to provide a built-in feature or script to extract a project-wide CFG, including inter-procedural information. The solution should be capable of generating and visualizing the CFG for all functions, including the connections between different functions, in a user-friendly manner.

Describe alternatives you've considered
I have considered merging the CFG of each function with additional steps but I think it can be less accurate. How to use Joern script to achieve this? Thanks
