Macro Cchair[8]

This macro typesets the saturated carbon sixring in its most favorable conformation. The axial and equatorial bond lines to the substituents are always drawn by this macro, even when there is no substituent in a particular position. This is the usual practice in drawing the chair form.

The eight arguments represent the respective substituent formulas R1R8.
