function db=cosmo_meeg_layout_collection()
% return supported MEEG channel layouts
%
% db=cosmo_meeg_layout_collection()
%
% Output:
%     db            Nx1 cell for N layouts. Each elements has the following
%                   fields:
%                   .pos      Mx2 x and y coordinates for M channels
%                   .width    Mx1 width of channel
%                   .height   Mx1 height of channel
%                   .label    Mx1 cell string with channel labels
%                   .name     string with filename of layout

% Note:
%   - this function requires FieldTrip, as it uses its collection of
%     layouts
%   - the output from this function is similar to FieldTrip's
%     ft_prepare_layout.
%   - this function caches previously read layouts, for optimization
%     reasons. run "clear functions" to reset the cache.
