/**

 * Template class implements token replacement logic for strings containing HTML and tokens.

 *

 * The following format is used for tokens: #{token_name}.

 * When found in template String, token will be replaced with value of the key "token_name" of object passed to

 * evaluate function. All occurrences of tokens are replaced by values from object with HTML entities escaped.

 * Token name should be prefixed with character '*' to avoid escaping of HTML entities (for example, #{*test}).

 * Backslash character (\\) can be used to escape token (such tokens will not be affected).

 *

 * Nested object properties could be used in templated by using square bracket token syntax (for example, #{a[b][c]}).

 * Previous example will look for nested value a->b->c ({'a': {'b': {'c': 'value'}}}).

 *

 * @param {string} template    template string

 *

 * @return {Template}
