Import/Export JSON and Code Generator

The "Keyboard Shortcuts" topic under "Reference" in Help lists several recently added shortcut keys for importing and exporting case inputs to and from JSON. These were originally implemented for internal use:

• Ctrl-F5 Save case inputs as JSON
• Ctrl-F6 Load case inputs from JSON file
• Ctrl-F7 Save case inputs as JSON for SSC
• Ctrl-F8 Load case inputs from JSON for SSC file
• Ctrl-F9 Load case inputs from JSON for SSC file and run simulation

Need to test and provide more usable ways to access these features.

Considerations:

• Add "Export to JSON" and "Import from JSON" commands to Case menu to make it easier for users to find
• Export additional metadata to JSON such as performance/financial model name, SAM/ssc version number, etc.
• Compare to code generator options, and consider replacing code generator with these tools. "Export to JSON" command on Case menu could replace "Generate code"

Start with the Keyboard Shortcuts topic under Reference and the existing Ctrl-F5–Ctrl-F9 import/export commands. Compare those commands with the Case menu and code generator options, then clarify the metadata and replacement scope; done requires an agreed, tested, discoverable workflow.
