[SCIP] Default Plugins - branch&price

[Benjamin Müller]

Dear Albert,

did you include your plug-ins by using the corresponding include 
function (SCIPincludeObjBranchrule)? If you just want to use your 
branching rule you need to give it the highest priority.

Alternatively, you can remove SCIPincludeDefaultPlugins and explicitly 
include only the plug-ins you want to use. Note that you need to have at 
least one node selector.

Regards,
Benny
