function [col,varargout]=getcolors(colorscheme,varargin);
% Returns a color or a sequence of colors.
% The sequence can be accessed through a variable amount of output arguments
% (each one containing a character representing a color), or through a string.
%
% Syntax: (* = optional)
%
% [color, color2, color3, ...] = getcolors(colorscheme);
% colorseq = getcolors(colorscheme, n);
%
% In arguments:
%
% 1. colorscheme
%	An integer that is used for calculating the color sequence. Different values
%	give different sequences.
% 2. n
%	Amount of colors in the resulting sequence of colors (the 'colorseq' output argument)
%
% Out arguments:
%
% 1. color, color2, color3, ...
%	A character representing a color. Matlab standards are used, so for instance
%	'b' means blue and 'g' means green (see the documentation of the plot command
%	for a list of colors).
% 1. colorseq
%	A string containing a sequence of colors (characters).
