First version checked in

It's simple. It stores DICOM files. It's SimpleDICOMStorage.

1. We can listen on multiple ports. Each port has an AE Title.
2. A storage strategy can be associated with each port. The strategy allows you to define which tags are used to construct the path under while files are stored.
3. I'm now working on the modalityRule idea. This allows us to write out files in a specified transfer syntax based on the modality tag in the dataset. EXPERIMENTAL FOR NOW.

Here is a sample configuration ...

<?xml version="1.0" encoding="utf-8" ?>

<simpleDICOMStorage>

<listeners>

<listener port="32760" aeTitle="COLINSPC">

<listener port="32761" aeTitle="AnotherAE">
  <storage root="c:\temp\AnotherAE" strategy="patientCentric" modalityRuleSet="decompress"/>
</listener>

</listeners>

Modality rules specify actions to use when an image with that

every modality and is used if no other modality match exists.

   Modality rules are applied on a per AE basis.
