Bug 12603: creating TestBuilder to simplify tests 

This patch contains a new module t::lib::TestBuilder which allows to write tests easier and it contains the unit tests of this module.
For more information, see the documentation of the module.

This module uses the DBIx::Class schema and works with a clean DBIx::Class schema. In order to use it, you have to remove the current circular dependence (existing in the DBIx::Class) by applying the last patch of the bug 11518.

=head1 NAME
t::lib::TestBuilder.pm - Koha module to simplify the writing of tests
=head1 SYNOPSIS
use t::lib::TestBuilder;
Koha module to insert the foreign keys automatically for the tests
=head1 DESCRIPTION
This module allows to insert automatically an entry in the database. All the database changes are wrapped in a transaction.
The foreign keys are created according to the DBIx::Class schema.
The taken values are the values by default if it is possible or randomly generated.
=head1 FUNCTIONS
=head2 new
$builder = t::lib::TestBuilder->new()
Constructor - Begins a transaction and returns the object TestBuilder
=head2 schema
$schema = $builder->schema
Getter - Returns the schema of DBIx::Class
=head2 clear
$builder->clear({ source => $source_name })
=over
=item C<$source_name> is the name of the source in the DBIx::Class schema (required)
=back
Clears all the data of this source (database table)
=head2 build
$builder->build({
source => $source_name,
value => $value,
only_fk => $only_fk,
})
=over
=item C<$source_name> is the name of the source in the DBIx::Class schema (required)
=item C<$value> is the values for the entry (optional)
=item C<$only_fk> is a boolean to indicate if only the foreign keys are created (optional)
=back
Inserts an entry in the database by instanciating all the foreign keys.
The values can be specified, the values which are not given are default values if they exists or generated randomly.
Returns the values of the entry as a hashref with an extra key : _fk which contains all the values of the generated foreign keys.
