A SoS Jupyter notebook accepts the following types of cells:

• Markdown cells that can be rendered to have title, table etc
• Subkernel cells with statements in other languages with optional SoS magics at the beginning of the cells
• SoS cells with SoS statements without any section header
• Workflow cells with SoS statements and section header. These cells can only be executed by magic %run, %sosrun, or command sos run from command line
