request for release new version

[k-okada]

since current released version has serious problem on reading numbers (#5) and this has been fixed in 669917e

so could you release new version?

Thanks in advance

NOTE : please merge #11 before you release new version

@jbohren How about this issue?
By this huge bug of apt version of xdot, smach_viewer does not work at all.
Please note that we should merge #12 and #14 (moved from #11 ) before releasing new version.
