Pang-bô͘:Year nav topic/doc

Format: {{Year nav topic|year#|subject}}

Takes two parameters, the year# (year 101 or higher), followed by the subject (such as: music), separated by vertical bars:

The year# becomes the bolded center of the 20-year range for the subject.
For the subject "xxx" there should be a specific article (or redirection) using the name "List_of_years_in_xxx" (which is the top line displayed in the navigation-box).
For the subject "xxx" there should be a specific all-years navigation article using the name "Table_of_years_in_xxx" (the "Table" link displayed in box), which has a compressed table linking all year/decade articles about the subject (such as: "Table of years in film").
The box width shrinks 0% (unchanged) for smaller year-number sizes, since width is determined by the subject-list (bottom line).
