diff audioDB.cpp @ 171:bb934f91d85c powertable

Web services interface to the powertable functionality.

* Implemented as a completely new SOAP method, called sequenceQuery
* lightly tested with http://doc.gold.ac.uk/~mas01cr/poweradb.php

(lacuna: need to pass relative-threshold and absolute-threshold always,
even when they don't make sense.)

Several uglinesses in the code, some of which will be resolved once all
the various branches are merged into the trunk.
