Various changes. SST refactoring which I'm not sure is worth it because I'm pretty sure SST recordsize calculation is all wrong. Added some logging stuff and also merged some stuff from 1.5 branch

<section title="HSSF Logging facility">
|

<p>HSSF now has a logging facility (using
|
||||
<link href="http://jakarta.apache.org/commons/logging.html">commons logging</link>)
|
||||
that will record massive amounts of debugging information. Its mostly
|
||||
useful to us hssf-developing geeks, but might be useful in tracking
|
||||
down problems.
|
||||
</p>
|
||||
<p>So Why use commons logging rather than log4j? Well the following discussion from
|
||||
the jakarta-general mailing list sums it up pretty well. (Thanks Morgan)
|
||||
</p>
|
||||
<p><em>Here's the problem, as I see it.</em>
|
||||
</p>
|
||||
<p><em>Suppose Commons component A decides to adopt Log4J, Commons component B
|
||||
decides to adopt LogKit, and Commons component C adopts JDK1.4 logging.
|
||||
They will all minimally function with the right jars in the classpath.
|
||||
However you (the end-user) are left with maintaining configuration for 3
|
||||
different logging APIs, which is tedious at best. When you take into
|
||||
account cool features like variable log levels, Log4J appenders and the
|
||||
like, you're pretty much guaranteed to swallow up useful configuration
|
||||
options because sophisticated configurations are too difficult to maintain
|
||||
over mutiple logging implementations.</em>
|
||||
</p>
|
||||
<p>
|
||||
<em>Contrarily, if all three Commons components use a logging facade, you can
|
||||
focus all your configuration efforts on one logging implementation. Sure,
|
||||
there is a trade-off; you don't have access to all the features, and the
|
||||
interface between the facade and the implementation must be maintained. But
|
||||
the benefits are not just political; they potentially make the end-users
|
||||
configuration much easier.</em>
|
||||
</p>
|
||||
<p><em>Even if all Commons components used the same logging implementation (Log4J
|
||||
for example), other projects in Jakarta-land may choose otherwise. If you
|
||||
add enough Jakarta projects to your environment, you eventually end up with
|
||||
the scenario described above. It's a worthwhile effort to attempt a logging
|
||||
solution that plays well with the Jakarta community at large. I think in
|
||||
many cases the Commons Logging component can fill that role.</em>
|
||||
</p>
|
||||
<p>

||||
Refer to the commons logging package level javadoc for more information concerning how to
|
||||
<link href="http://jakarta.apache.org/commons/logging/api/index.html">configure commons logging.</link>
|
||||
</p>
|
||||
<section title="Logging facility">
|
||||
<p>Poi can dynamically select it's logging implementation. Poi trys to
|
||||
create a logger using the System property named "org.apache.poi.util.POILogger".
|
||||
Out of the box this can be set to one of three values:

<ul>
