page mappings

Each page.py has a mapping list of dictionaries and they look like:

mapping = [
    {"type": "markdown", "file": "markdown/raw_spot_data.md"},
    {"type": "pycode", "file": "dataframes/spot_curve_data.py"},
    {"type": "dataframe", "table_html": df },
]

however a mapping in render.py also takes the following from the page.py

meta = {"name": "Raw_Spot_Data", "nav_order": 1000}

we call this combe of 3 items a mapping nav order; name; and a mapping list of dictionaries.

a page mapping is the mapping list of dicitionarieis within a mapping
