Writing good methods/functions:
	* Naming
		* Give descriptive names that say exactly what the routine does (usually verb-noun)
		* The name should include or imply the return type
	* Lines of code
		* Functions over a couple hundred lines of code tend to be more error-prone
		* Otherwise, no hard constraints on method length - whatever is natural for the situation
	* Parameters
		* Use parameter order consistently among different functions
		* Document assumptions on parameters
		* Document units
		* Document zero-based-counting vs one-based-counting if not obvious
	* Error handling
		* Check values of input parameters
		* Use assertions to check for bugs.  Use error handling to check for bad input.
		* Techniques for error handling:
			* Return null or neutral value
			* Print or log the error and continue execution
			* Throw an exception/error
			* Terminate the program
