        Construct a URI from the component parts each of which may contain template variables.

        The template values are an array of Object and each Object instance MUST support the toString() method to convert the template value to a String instance.

        Parameters:
        scheme - the URI scheme component.
        authority - the URI authority component.
        userInfo - the URI user info component.
        host - the URI host component.
        port - the URI port component.
        path - the URI path component.
        query - the URI query component.
        fragment - ] the URI fragment component.
        values - the array of template values.
        encode - if true encode a template value according to the correspond component type of the associated template variable, otherwise contextually encode the template value.
        encodeSlashInPath - if true, the slash ('/') characters in parameter values will be encoded if the template is placed in the URI path component, otherwise the slash characters will not be encoded in path templates.
        Returns:
        a URI.
