Generate multiple templates from one stream of data.

Thin wrapper around _template_gen to generate multiple templates from
one stream of continuous data.  Takes processed (filtered and resampled)
seismic data!

:type catalog: obspy.core.event.Catalog
:param catalog: Events to extract templates for
:type st: obspy.core.stream.Stream
:param st:
    Processed stream to extract from, e.g. filtered and re-sampled to what
    you want using pre_processing.dayproc.
:type length: float
:param length: Length of template in seconds
:type swin: string
:param swin:
    P, S, P_all, S_all or all, defaults to all: see note in
    :func:`eqcorrscan.core.template_gen.template_gen`
:type prepick: float
:param prepick:
    Length in seconds to extract before the pick time default is
    0.05 seconds.
:type all_horiz: bool
:param all_horiz:
    To use both horizontal channels even if there is only a pick on one of
    them.  Defaults to False.
:type delayed: bool
:param delayed:
    If True, each channel will begin relative to it's own pick-time, if set
     to False, each channel will begin at the same time.
:type plot: bool
:param plot: To plot the template or not, default is True
:type debug: int
:param debug: Debug output level from 0-5.
:type return_event: bool
:param return_event: Whether to return the event and process length or not.
:type min_snr: float
:param min_snr:
    Minimum signal-to-noise ratio for a channel to be included in the
    template, where signal-to-noise ratio is calculated as the ratio of
    the maximum amplitude in the template window to the rms amplitude in
    the whole window given.

:returns: List of :class:`obspy.core.stream.Stream` templates.
:rtype: list

.. warning::
    Data must be processed before using this function - highcut, lowcut and
    filt_order are only used to generate the meta-data for the templates.

.. note:: By convention templates are generated with P-phases on the \
    vertical channel and S-phases on the horizontal channels, normal \
    seismograph naming conventions are assumed, where Z denotes vertical \
    and N, E, R, T, 1 and 2 denote horizontal channels, either oriented \
    or not.  To this end we will **only** use Z channels if they have a \
    P-pick, and will use one or other horizontal channels **only** if \
    there is an S-pick on it.

.. warning:: If there is no phase_hint included in picks, and swin=all, \
    all channels with picks will be used.
