1. Integrate PUI to modmesh and make a JSON editor for configuration.

   The JSON editor will be used for manipulating the modmesh toggle system. We need to figure out what GUI widgets are needed.

   modmesh toggle does not have documentation yet. The best description to it is:

   modmesh/cpp/modmesh/toggle/toggle.hpp

   Line 218 in b892a80

   /**

2. Fix the MacOS CI failure (CI fail to find Numpy with pip install #213) and make the CI more robust.

   Terry made some progress and updated on discord

   The issue also tracks another issue induced by @j8xixo12 turning on MODMESH_USE_PYSIDE to let modmesh to build with pyside6 by default. GitHub Actions fails on every platforms with different reason. @j8xixo12 is working on it

3. Profiling system: Add profiling system for the shock tube problem #135

   Modmesh has a profile system in https://github.com/solvcon/modmesh/blob/master/cpp/modmesh/toggle/profile.hpp

   @q40603 proposed an idea to use LLVM to insert the profiling macros during compilation. It needs further discussions.

4. mesh processing

   Mesh processing needs lots of work on GUI and file I/O. We can reference the legacy implementation https://github.com/solvcon/solvcon to see how much work is ahead.

5. Data storage and post processing.

   It is related to mesh processing. In the same way, we can reference the legacy implementation https://github.com/solvcon/solvcon to see how much work is ahead.
