Subject: create class to hold drawing information
X-Git-Url: http://woldlab.caltech.edu/gitweb/?p=mussa.git;a=commitdiff_plain;h=a5fdb434dd0e6d18fe98e9ee57cb5169ce4c5842

create class to hold drawing information
this will be added to SeqSpan to add information needed to draw
stuff on the screen--only if a particular SeqSpan is being rendered.
