which by default calculates all possible indices,
this function will only calculate the index value.By default calculates formula D by McLaughlin (1969).
If parameters is set to SMOG="C", formula C will be calculated.
If parameters is set to SMOG="simple", the simplified formula is used, and
if parameters="de", the formula adapted to German texts ("Qu", Bamberger & Vanecek,
1984, p. 78).
