;
; Function:			Eval
; Description:		Evaluate Expressions in Strings.
; Return value:		An array (object) with the result of each expression.
;
; Author:			Pulover [Rodolfo U. Batista]
; Credits:			ExprEval() by Uberi
;
;=======================================================================================
;
; Parameters:
;
;	$x:				The input string to be evaluated. You can enter multiple expressions
;						separated by commas (inside the string).
;	_CustomVars:	An optional Associative Array object containing variables names
;					  as keys and values to replace them.
;					For example, setting it to {A_Index: A_Index} inside a loop will replace
;						occurrences of A_Index with the correct value for the iteration.
;	_Init:			Used internally for the recursive calls. If TRUE it resets the static
;						object _Objects, which holds objects references to be restored.
