Re: unused local variables

Hello,

I have created two checkers:

<module name="cs.UnusedLocalVariable" />
	This checker detects unused local variable.


<module name="cs.TooEarlyVariableDeclaration" />

	This checker detects several things about variable declaration.
Examples:
	int i = 0, j = 4; // Error: Declare variables on separate lines

	int i;
	i = 4;  // those two lines can be merged into "int i = 4"


	int i = 0; // this affectation is useless
	i = 4;

	int i; // Declare variable as close as possible to where they are
used
	[A lot of code that does not use i]
	i = 6;

I've attached the "cs.jar" file that is needed to used thoses checkers.
(sources are included).

The checkers have *not* been extensively tested, so use them with care.

Hope this helps!
