function value = findArg( argname, varargin )
%findArg  Find a specific property value from a property-value pairs list
%
%   value = findParentArg(propname,varargin) parses the inputs as property-value
%   pairs looking for the named property. If found, the corresponding
%   value is returned. If not found an empty array is returned.

%   Examples:
%   >> uiextras.findArg('Parent','Padding',5,'Parent',1,'Visible','on')
