The organization of a template looks like this:

"sheet":{
  "configuration":{
    ...
  },
  "section":
    "configuration":{
    ...
  },
  "group":{
    "configuration":{
    ...
  },
      "field":{
        ...
      }
  }
	
}

• Sheet is the main object.
• Section is a division of sheet.
• Group is a division of sections. May be considered as columns.
• Field is the atomic unit of information of the sheet.
• Configuration sets the parameters to the specific hierarchy.
