 The <a href="hgBamTrackHelp.html" target="_blank">BAM track configuration</a> help page describes 
 the BAM track configuration page options corresponding to <code>pairEndsByName</code>,
 <code>minAliQual</code>, <code>bamColorMode</code>, <code>bamGrayMode</code> and
 <code>bamColorTag</code> in more detail.</p>
 <p>
 <code>pairSearchRange</code> applies only when <code>pairEndsByName</code> is given. It allows for 
 a tradeoff of display speed vs. completeness of pairing the paired-end alignments. When paired ends 
 are split or separated by large gaps or introns, but one is viewing a small genomic region, it is 
 necessary to search a large number of bases upstream and downstream of the viewed region in order 
 to find mates of the alignments in the viewed region. However, searching a very large region can be 
 slow, especially when the alignments have deep coverage of the genome. To ensure that all properly 
 paired mates will be found, <code>pairSearchRange</code> should be set to the largest genomic size
