=head1 NAME

Bio::EnsEMBL::Variation::ReadCoverageCollection - A collection of coverage reagion for a read.

=head1 SYNOPSIS

    # Read coverage collection feature representing a genomic region covered by a read

    $rcc = Bio::EnsEMBL::Variation::ReadCoverageCollection->new
       (-start   => 100,
        -end     => 200,
        -strand  => 1,
        -slice   => $slice,
        -window_start => 1,
        -window_end => 1000,
        -window_size => 50,
        -read_coverage_avg => 100,
        -read_coverage_min => 0,
        -read_coverage_max => 200,
        -sample  => $individual);


    print $rcc->start(), "-", $rcc->end(), "\n";


=head1 DESCRIPTION

This is a class representing the read coverage collection information
from the ensembl-variation database. A ReadCoverageCollection behaves as any other Ensembl feature collection.
Object for storing read_coverage scores. The scores are averaged (also the minimum and maximum scores) over different window sizes to speed up drawing over large regions. The scores are packed as integer and stored in a string
See B<Bio::EnsEMBL::Feature>.
