personal dictionary name. A new jspell dictionary object will be
returned.

=head2 nearmatches

This method returns a list of analysis for words that are near-matches
to the supplied word. Note that although a word might exist, this
method will compute the near-matches as well.

  @nearmatches = $dictionary->nearmatches('cavale');

To compute the list of words to analyze, the method uses a list of
equivalence classes that are present on the C<< SNDCLASSES >> section
of dictionaries yaml files.

It is also possible to specify a list of user-defined classes. These
are supplied as a filename that contains, per line, the characters
that are equivalent (with spaces separating them):

   ch   x
   ss   ç

This example says that if a word uses C, then it can be replaced
by C for near-matches calculation. The inverse is also true.

If these rules are stored in a file named C, you can
supply this list with:

  @nearmatches = $dictionary->nearmatches('chaile', rules => 'classes.txt');

=over 4

=item af

(add flags) Enable parcial near misses, by using rules not officially
associated with the current word.  Does not give suggestions by
changing letters on the original word.  (default option)

=item full

(add flags and change characters) Enable near misses, try to use rules
where they are not applied, try to give suggestions by swapping
adjacent letters on the original word.

=item cc

(change characters) Enable parcial near misses, by swapping adjacent,
inserting or modifying letters on the original word.  Does not use
rules not associated with the current word.

=item off

Disable near misses at all.

If a restriction is provided, just the analisys that verify
