SpreadsheetCompiler generates wrong LHS order

When a Spreadsheet (xls) has CONDITION columns like:

• The first column doesn't have Fact (e.g. accumulate(...))
• The second column has Fact (e.g. $p:Person(...))
  (See attached LhsOrder.xls)

, SpreadsheetCompiler generates a DRL with inverse order in LHS.

rule "LhsOrder_11"
	when
		$p:Person(name == "John", age == $max)
		accumulate(Person(name == "John", $a : age); $max:max($a))
	then
		System.out.println("hello, " + $p.getName());
end
