Subject: Define analysis scroll area implementation
X-Git-Url: http://woldlab.caltech.edu/gitweb/?p=mussa.git;a=commitdiff_plain;h=816d629a4848d570ee906bb5dfadeab88f3edafa

Define analysis scroll area implementation

 * Define analysis now uses a scroll area so when you add more than 3 SequenceWidgets it automatically scrolls, allowing many more sequences to be added.
 * See ticket:56 for more information.
