[Task] Update Cycstub archetype development pages

What is this task about?

Provide updates to the arche/hello_world_cpp.rst and arche/tutorial_cpp/* to be more clear for a user.

• arche/hellow_world.rst:

• Make it clear to a user to create tutorial directory and move to that directory before running cycstub command

• arche/tour_cpp.rst:

• In the section with cycstub commands, part of the input is the path: [path]:[library-name]:[archetype-name]
  but the path part is missing
• When you start talking about the "implementation file", remind the reader that this is the .cc file created
• Jumps from the .cc file back to the .h file -- should discuss all of the contents of the .h file then talk about the .cc file

• arche/tutorial_cpp/setup.rst:

• I'm not sure if the install_cyclus_standalone command the page tells you to use still works because after I do that and reinstall (need to update the command to install on the page) I get an error: Storage_unit_tests: error while loading shared libraries: libStorage.so: cannot open shared object file: No such file or directory
• If we are are going to remove the install_cyclus_standalone, should we update it to USE_CYCLUS(...) in the first part of the src/CMakeLists.txt file?
• If we have users set the verbosity to 2 when they run the storage example input file, the terminal output should include the time step number:

INFO1(core  ):Current time: 0
Hello, World!
 INFO1(core  ):Current time: 1
Hello, World!
 INFO1(core  ):Current time: 2
Hello, World!

• arche/tutorial_cpp/state_var.rst:

• Update install command
• Update terminal output when running example with verbosity of 2 (see above)

• arche/tutorial_cpp/toolkit.rst:

• Update install instructions

Why is this task needed?

Routine documentation updating

Relevant resources or references

How can this issue be closed?

Start by reviewing arche/hello_world_cpp.rst, arche/tour_cpp.rst, and the files under arche/tutorial_cpp/, focusing on the current install commands and cited CMake usage. Reproduce the setup and storage example with verbosity 2 to verify the reported library error and expected output. Done means the pages contain working install instructions, clear paths and file explanations, and updated terminal output.
