function tpl = template(root,unknowns)
%TEMPLATE HTML Template Toolbox Constructor
%  TPL = TEMPLATE returns a template object using default values for the
%  root path of the template files ('.') and for the way of handling unknown
%  replacement fields (default is 'remove').
%  TPL = TEMPLATE(ROOT) allows to specify the root path of the template files
%  that will then be provided relative to this path.
%  TPL = TEMPLATE(ROOT,UNKNOWNS) also allows to specify the strategy to apply
%  to unkown fields. UNKNOWNS may be:
%    * 'keep' to do nothing
%    * 'remove' to remove all undefined fields
%    * 'comment' to replace undefined fields by a warning HTML comment.
%
%  The template class allows you to keep your HTML code in some external 
%  files which are completely free of Matlab code, but contain replacement 
%  fields. The class provides you with functions which can fill in the 
%  replacement fields with arbitrary strings. These strings can become very 
%  large, e.g. entire tables.
