/**
 * Convert a numerical version in decimal form (i.e. 0.4.1) to a long
 * that respects natural version number ordering. For example, the long
 * conversion for 0.5.0 is guaranteed to be greater than the long
 * conversion for 0.4.1./*from   www .  j a  v  a  2 s .c  om*/
 * <p>
 * The {@code maxComponentLength} parameter is used to ensure that each
 * component of the version has the necessary padding. You should specify
 * this value to be the largest possible length of a version number
 * component in your scheme (i.e. for version A.B.C if component C may
 * possible go up as high as 999, then you should specify 3 for the
 * maxComponentLength value).
 * </p>
 * <p>
 * <strong>Warning:</strong>If one or more of the component lengths is
 * greater than {@code maxComponentLength} then this method will use the
 * larger component length in its calculation. This may potentially lead to
 * unexpected results, so its best to specify the {@code maxComponentLength}
 * to be sufficiently large.
 * </p>
 * 
 * @param version
 * @param maxComponentLength
 * @return the long representation of the version
