=head1 NAME

Bio::Variation::SNP - submitted SNP

=head1 SYNOPSIS

  $SNP = Bio::Variation::SNP->new ();

=head1 DESCRIPTION

Inherits from Bio::Variation::SeqDiff and Bio::Variation::Allele, with 
additional methods that are (db)SNP specific (ie, refSNP/subSNP IDs, batch
IDs, validation methods).

=head1 FEEDBACK

User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to the 
Bioperl mailing lists  Your participation is much appreciated.

=head2 is_subsnp

 Title   : is_subsnp
 Usage   : $is = $snp->is_subsnp()
 Function: returns 1 if $snp is a subSNP
 Returns : 1 or undef
 Args    : NONE

=cut

 Title   : subsnp
 Usage   : $subsnp = $snp->subsnp()
 Function: returns the currently active subSNP of $snp
 Returns : Bio::Variation::SNP
 Args    : NONE

=head2 add_subsnp

 Title   : add_subsnp
 Usage   : $subsnp = $snp->add_subsnp()
 Function: pushes the previous value returned by subsnp() onto a stack, accessible with each_subsnp().
           sets return value of subsnp() to a new Bio::Variation::SNP object, and returns that object.
 Returns : Bio::Varitiation::SNP
 Args    : NONE

=head2 each_subsnp

 Title   : each_subsnp
 Usage   : @subsnps = $snp->each_subsnp()
 Function: returns a list of the subSNPs of a refSNP
 Returns : list
 Args    : NONE
