%XB_GENERATE_SETTINGS  Generates a XBeach structure with model settings
%
%   Generates a XBeach structure with model settings. A minimal set of
%   default settings is used, unless otherwise provided. Settings can be
%   provided by a varargin list of name/value pairs.
%
%   Syntax:
%   xb = xb_generate_settings(varargin)
%
%   Input:
%   varargin  = Name/value pairs of model settings (e.g. 'nx',100,'ny',200)
%
%   Output:
%   xb        = XBeach structure array
%
%   Example
%   xb = xb_generate_settings()
%   xb = xb_generate_settings('nx', 100, 'ny', 200)
