Added the following formula functions:

Browse Source 
- Min: get the lowest value
  - Max: get the highest value
  - CountE: count the number of empty cells
  - CountNE: count the number of non-empty cells
  - PercentE: percent of empty cells
  - PercentNE: percent of non-empty cells
  - AverageNE: average over non-empty cells

Also added a subtle tweak that ignores an HTML comment tag ('<!--')
found between the table and the starting formula line. Being able to
wrap all the formula lines with an HTML comment prevents the formulas
from being rendered in Markdown/ReST output.
