 *   Modified:    30-Aug-05    Alexandre A. Del Savio
 *     Adicionado o atributo pilot na estrutura sNode. Este atributo
 *     define, quando for igual a 1, se o nó possui deslocamento
 *     prescrito na primeira interacao e nas interacoes seguintes passa
 *     a ser OBJECT. 
 *
 *   Modified:    14-Set-06    Juan Pablo Ibanez
 *     Criada a estrutura sInfoConst para a constrain associada aos nos,
 *     a qual passa a ser utilizada no campo constrain de sNode.
