=head1 all_entities_ProbeSet
Return all instances of the ProbeSet entity.
A probe set is a device containing multiple probe sequences for use
in gene expression experiments.
Example:
    all_entities_ProbeSet -a 
would retrieve all entities of type ProbeSet and include all fields
in the entities in the output.
=head2 Related entities
The ProbeSet entity has the following relationship links:
=over 4
     
=item GeneratedLevelsFor AtomicRegulon
=item HasResultsIn Experiment
=item IndicatedLevelsFor Feature
=item ProducedResultsFor Genome
=back
=head2 Command-Line Options
=over 4
=item -a
Return all fields.
=item -h
Display a list of the fields available for use.
=item -fields field-list
Choose a set of fields to return. Field-list is a comma-separated list of 
strings. The following fields are available:
=over 4
=back

=head2 Output Format
The standard output is a tab-delimited file. It consists of the input
file with an extra column added for each requested field.  Input lines that cannot
be extended are written to stderr.
