Foo function square no make sense

[Stephen Siegel]

It looks like it is squaring the value of the left hand side and returning that in the left hand side. It is not reading the parameter passed to the function...

		} else if (name.equals("square")) {
			// Execute square. This returns the square root of the parameter.
			
			// Huh????
			
			LHSExpressionIF lhs = invocation.lhs();
			if (lhs != null && lhs instanceof VariableExpressionIF) {
				try {
					assignValue(environment, lhs, evaluator.dynamicFactory()
							.multiply(
									environment.getAssumption(),
									environment.valueOf(evaluator.cell(
											environment,
											((VariableExpressionIF) lhs)
													.variable())),
									environment.valueOf(evaluator.cell(
											environment,
											((VariableExpressionIF) lhs)
													.variable()))), evaluator);

Fixed both the assignment and the comment (square, not square root).
