VBAPSynthdefs - slightly change of syntax
VBAPLib refactor
correct WFSPointGroup for use in synthdefs
load UMapDefs at WFSLib:startup
implement WFSSpeakerConf:focusWidth

this can set focus wider for very large tunnel setups. Set to 2pi for
single array setups
use focusWidth in plotting examples
correct behavior of unitSize in WFSSpeakerConfGUI
correct focusWidth for wfsDynamicPoint
introduce WFSArrayConf:oppositeDist

to be used for correct focus detection on partial setups
add wfsPathPlayer UMapDef

paths can now also be used as UMapDefs. Perhaps this should become the
default procedure for WFSPaths.
