<h2>Breakpoint</h2>

<p>
    Breakpoint class.
</p>
<p>
    Implements temporary breakpoints, ignore counts, disabling and
    (re)-enabling, and conditionals.
</p>
<p>
    Breakpoints are indexed by the file,line tuple using breaks. It
    points to a single Breakpoint instance. This is rather different to
    the original bdb, since there may be more than one breakpoint per line.
</p>
<p>
    To test for a specific line in a file there is another dict breakInFile,
    which is indexed only by filename and holds all line numbers where
    breakpoints are.
