merge in skip seq feature

@@ -16,6 +16,7 @@ Attributes:
 * context_len - The number of tokens in the model context window, or None
 * modality - A dictionary with two keys, "in" and "out", each holding a set of the modalities supported by the generator. "in" refers to prompt expectations, and "out" refers to output. For example, a text-to-text+image model would have modality: ``dict = {"in": {"text"}, "out": {"text", "image"}}``.
 * supports_multiple_generations - Whether or not the generator can natively return multiple outputs from a prompt in a single function call. When set to False, the ``generate()`` method will make repeated calls, one output at a time, until the requested number of generations (in ``generations``) is reached.
+* skip_seq_start, skip_start_end - If both asserted, content between these two will be pruned before being returned. Useful for removing chain-of-thought, for example

@@ -32,12 +33,20 @@ The general flow in ``generate()`` is as follows:
   #. Otherwise, we need to assemble the outputs over multiple calls. There are two options here.
     #. Is garak running with ``parallel_attempts > 1`` configured? In that case, start a multiprocessing pool with as many workers as the value of ``parallel_attempts``, and have each one of these work on building the required number of generations, in any order.
     #. Otherwise, call ``_call_model()`` repeatedly to collect the requested number of generations.
+  #. Call the ``_post_generate_hook()`` (a no-op by default)
+  #. If skip sequence start and end are both defined, call ``_prune_skip_sequences()``
   #. Return the resulting list of prompt responses.
 
+
 #. **_call_model()**: This method handles direct interaction with the model. It takes a prompt and an optional number of generations this call, and returns a list of prompt responses (e.g. strings) and ``None``s. Models may return ``None`` in the case the underlying system failed unrecoverably. This is the method to write model interaction code in. If the class' supports_multiple_generations is false, _call_model does not need to accept values of ``generations_this_call`` other than ``1``.
 
 #. **_pre_generate_hook()**: An optional hook called before generation, useful if the class needs to do some setup or housekeeping before generation.
 
+#. **_verify_model_result**: Validation of model output types, useful in debugging. If this fails, the generator doesn't match the expectations in the rest of garak.
+
+#. **_post_generate_hook()**: An optional hook called after generation, useful if the class needs to do some modification of output.
+
+#. **_prune_skip_sequences()**: Called if both ``skip_seq_start`` and ``skip_seq_end`` are defined. Strip out any response content between the start and end markers.
