Error in ioapiTools test
<p>I've just installed <code>ioapiTools</code> and when I run the test provided with the package to make everything works ok, I get a series of errors, all linked to the first one: </p>

<pre><code>File "unit_ioapiTolls.py", line 138 in testReadvar
 self.failUnless(f("o3"), "read variable from ioapi file failed")
......
ValueError: the truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
</code></pre>

<p>So it seems that the script is failing to read in a variable. I've checked the paths and folders in question and everything seems in place. Furthermore, I've opened a separate python window and run the test command lines that seem to be causing the error and it works fine. I can read in the variable and then perform the remaining operations where the variable's value is passed on to and which cause the remaining errors. </p>

<p>So, as I see it, the problem seems to be with the test script (<code>unit_ioapiTools.py</code>) and not with <code>ioapiTools.py</code> itself! </p>

<p>Could this be?<br>
Am I missing something obvious here?</p>
