/**
 * Classe para validação dinâmica de formulários
 * Está classe depende dos arquivos base.js e enumerable.js do Prototype( http://prototype.conio.net )
 *
 *
 * Em sua página de formulários crie o Objeto Validate e adicione as validações:
 *
 * var objValidate = new Validate();
 * objValidate.addValidate( 'id_do_campo' , funcao_de_validação );
 *
 * Ex:
 *
 * var objValidate = new Validate();
 *
 * objValidate.addValidate( 'nuCPF'  , objValidate.cpf    , 'CPF invalido' );
 * objValidate.addValidate( 'nuCPF'  , objValidate.isnull , 'Campo de preenchimento obrigatorio' , false );
 * objValidate.addValidate( 'nuCNPJ' , objValidate.cnpj   , 'CNPJ invalido' );
 *
 * E na hora de submeter o formulário chamar objValidate.verify()
