Code formatting

Chris:

• no preferences about brace placement (I prefer "next line shifted", but I realize almost everyone else uses K&R style, so I don't complain or try to fight it)
• no 80 (or any) columns restrictions
• spaces rather than tabs
• 3 spaces
• readable (long) variable names
• generally speaking, Camel-case, no consecutive uppercase characters
• wherever possible, make variables final
• no spaces before parenthese
• one space after comma, no leading and trailing spaces
• 1 space before and after an equal sign
• When lines must be wrapped, prefer to align items being wrapped (e.g. params) rather than the "continuation indent"
