  FT_MULTIPLOTTFR plots the time-frequency representations of power or coherence
  in a topographical layout. The plots of the indivual sensors are arranged
  according to their location specified in the layout.
  Use as
    ft_multiplotTFR(cfg, data)
  The data can be a time-frequency representation of power or coherence
  that was computed using the FT_FREQANALYSIS or FT_FREQDESCRIPTIVES
  The configuration can have the following parameters:
    cfg.parameter        = field to be represented as color (default depends on data.dimord)
                           'powspctrm' or 'cohspctrm'
    cfg.maskparameter    = field in the data to be used for opacity masking of data
    cfg.maskstyle        = style used to masking, 'opacity', 'saturation' or 'outline' (default = 'opacity')
                           use 'saturation' or 'outline' when saving to vector-format (like *.eps) to avoid all
                           sorts of image-problems (currently only possible with a white backgroud)
    cfg.maskalpha        = alpha value between 0 (transparant) and 1 (opaque) used for masking areas dictated by cfg.maskparameter (default = 1)
    cfg.masknans         = 'yes' or 'no' (default = 'yes')
    cfg.xlim             = 'maxmin' or [xmin xmax] (default = 'maxmin')
    cfg.ylim             = 'maxmin' or [ymin ymax] (default = 'maxmin')
    cfg.zlim             = plotting limits for color dimension, 'maxmin', 'maxabs', 'zeromax', 'minzero', or [zmin zmax] (default = 'maxmin')
    cfg.gradscale        = number, scaling to apply to the MEG gradiometer channels prior to display
    cfg.magscale         = number, scaling to apply to the MEG magnetometer channels prior to display          = Nx1 cell-array with selection of channels (default = 'all'), see FT_CHANNELSELECTION for details
    cfg.refchannel       = name of reference channel for visualising connectivity, can be 'gui'
    cfg.baseline         = 'yes', 'no' or [time1 time2] (default = 'no'), see FT_FREQBASELINE
    cfg.baselinetype     = 'absolute', 'relative', 'relchange' or 'db' (default = 'absolute')
    cfg.trials           = 'all' or a selection given as a 1xN vector (default = 'all')              = 'yes', 'no' (default = 'no' if maskparameter given default = 'yes')
                           Draw a box around each graph
    cfg.hotkeys          = enables hotkeys (up/down arrows) for dynamic colorbar adjustment
    cfg.colorbar         = 'yes', 'no' (default = 'no')
    cfg.colormap         = any sized colormap, see COLORMAP
    cfg.comment          = string of text (default = date + zlimits)
                           Add 'comment' to graph (according to COMNT in the layout)
    cfg.showlabels       = 'yes', 'no' (default = 'no')
    cfg.showoutline      = 'yes', 'no' (default = 'no')
    cfg.fontsize         = font size of comment and labels (if present) (default = 8)
    cfg.interactive      = Interactive plot 'yes' or 'no' (default = 'yes')
                           In a interactive plot you can select areas and produce a new
                           interactive plot when a selected area is clicked. Multiple areas
                           can be selected by holding down the SHIFT key.
    cfg.renderer         = 'painters', 'zbuffer', ' opengl' or 'none' (default = [])
    cfg.directionality   = '', 'inflow' or 'outflow' specifies for
                           connectivity measures whether the inflow into a
                           node, or the outflow from a node is plotted. The
                           (default) behavior of this option depends on the dimor
                           of the input data (see below).
    cfg.layout           = specify the channel layout for plotting using one of
                          the supported ways (see below).
  For the plotting of directional connectivity data the cfg.directionality
  option determines what is plotted. The default value and the supported
  functionality depend on the dimord of the input data. If the input data
  is of dimord 'chan_chan_XXX', the value of directionality determines
  whether, given the reference channel(s), the columns (inflow), or rows
  (outflow) are selected for plotting. In this situation the default is
  'inflow'. Note that for undirected measures, inflow and outflow should
  give the same output. If the input data is of dimord 'chancmb_XXX', the
  value of directionality determines whether the rows in data.labelcmb are
  selected. With 'inflow' the rows are selected if the refchannel(s) occur in
  the right column, with 'outflow' the rows are selected if the
  refchannel(s) occur in the left column of the labelcmb-field. Default in
  this case is '', which means that all rows are selected in which the
  refchannel(s) occur. This is to robustly support linearly indexed
  undirected connectivity metrics. In the situation where undirected
  connectivity measures are linearly indexed, specifying 'inflow' or
  'outflow' can result in unexpected behavior.
  The layout defines how the channels are arranged and what the size of each
  subplot is. You can specify the layout in a variety of ways:
   - you can provide a pre-computed layout structure (see ft_prepare_layout)
   - you can give the name of an ascii layout file with extension *.lay
   - you can give the name of an electrode file
   - you can give an electrode definition, i.e. "elec" structure
   - you can give a gradiometer definition, i.e. "grad" structure
  If you do not specify any of these and the data structure contains an
  electrode or gradiometer structure (common for MEG data, since the header
  of the MEG datafile contains the gradiometer information), that will be
  used for creating a layout. If you want to have more fine-grained control
  over the layout of the subplots, you should create your own layout file.
  To facilitate data-handling and distributed computing you can use
    cfg.inputfile   =  ...
  If you specify this option the input data will be read from a *.mat
  file on disk. This mat files should contain only a single variable named 'data',
  corresponding to the input structure. For this particular function, the
  data should be provided as a cell array.
