HOR-1623 "It is not possible to import processes with more than 10mb" SOLVED

Issue:
    It is not possible to import processes with more than 10mb
Cause:
    DOMDocument::loadXML(), esta funcion no maneja bien los archivos grandes, es decir, si un nodo de texto es mas
    largo de 10 Mb, entonces lanza una excepcion
Solution:
    Se usa la constante LIBXML_PARSEHUGE
