       Bio::Graphics::ConfiguratorI - A sectioned map of configuration options (a map of maps),
       with a default section.  Intended to augment existing tag->value semantics (ie. of
       Bio::AnnotationCollectionI) for object-representation information (eg. foreground color),
       and for general interface preferences (eg. image width in gbrowse).


           # get a ConfiguratorI somehow
           my $fg_color = $configurator->get('fgcolor');


       This object contains various configuration parameters.  It is divided up into sections and
       tags.  This is essentially a multi-level map (section->tag->value).  There is also the
       concept of a default section which is referenced when no section is passed to the
       ConfiguratorI methods.

       The rest of the documentation details each of the object methods.  Internal methods are
       usually preceded with a _

        Title   : get_sections
        Usage   : my @values = $configurator->get_sections();
        Function: Returns a list of the valid sections except
                  the default or undef.
        Returns : A list of the sections which can be queried.
        Args    : (optional section as string, tag as string)

        Title   : get_tags
        Usage   : my @values = $configurator->get_tags();
                  my @values = $configurator->get_tags('dna');
        Function: Returns a list of tags for a given section
                  or only the default tags section if no section
                  is given.
        Returns : A scalar list of tags
        Args    :

        Title   : get
        Usage   : my $value = $configurator->get('height');
                  my $value = $configurator->get('dna','height');
        Function: Returns a tag value from a configurator from the
                  either the default "_general" section or from
                  a specified section or undef.
        Returns : A scalar value for the tag
        Args    : (optional section as string, tag as string)

        Title   : set
        Usage   : $configurator->set('fgcolor','chartreuse');
        Function: Set a value for a tag
        Returns : The old value of the tag
        Args    : (optional section as string, tag as string, value as scalar)

        Title   : get_and_eval
        Usage   : my $value = $configurator->get_and_eval('height');
                  my $value = $configurator->get_and_eval('dna','height');
        Function: This works like get() except that it is
                  also able to evaluate code references.  These are
                  options whose values begin with the characters
                  "sub {".  In this case the value will be passed to
                  an eval() and the resulting codereference returned.
        Returns : A value of the tag or undef.
        Args    : (optional section as string, tag as string)
