How to init shares
Once all your balances are taken into account - next step is to issue mutual fund units (shares):
1. Add-ons > Spreadsheet Fund > Setup > Initialize shares
2. Enter initial price per PIE
3. Add all shareholders and their shares and click "Initialize".
You should see new rows on the "Issuance" tab. And John, Sam and Alice will appear on the "Investors" tab with their equivalent shares (units)
