#***********************************************************************
=item B<arrays_to_hash($keys_ref, $values_ref)> - translate arrays to hash
Parameters: references to keys array and values array
Return: hash
If @$keys_ref is longer than @$values_ref - rest of keys filled with
C<undef> values.
If @$keys_ref is shorter than @$values_ref - rest of values are discarded.
If any of parameters isn't array reference then C<undef> will return.
Example:
my %h = array2hash(['fruit','animal'], ['apple','horse']);
Result should be a hash:
(
fruit => 'apple',
animal => 'horse'
)

#***********************************************************************
=item B<merge_hash($target, $source)> - merge two hashes
Parameters: references to target and source hashes.
This method adds source hash to target one and return value as a result.
