Perl implementation of DDR Simple API

I have uploaded a working draft [1] and highlighted version [2] of a
Perl implementation of the final DDR Simple API.

The purpose of this code is to illustrate the API implemented in another
of the programming languages that the DDWG identified as a target for
the API. The implementation is in a single file, although the file
itself represents several packages. It should execute on current Perl
systems. The expected output is given in comments at the end of the
source code.

The program contains some usage demonstrations, some convenience
wrappers around the standard API methods, and a set of API tests derived
from the previously presented Java test class.

The repository itself is also in the source code, in the form of a Perl
data structure and a set of access methods. In a deployed
implementation, one can expect that the actual repository would be an
external database or some other such dedicated system, for reasons of
performance, management, security etc. However, the program that I have
now delivered is entirely in Perl and thus can be examined in isolation.

The implementation claims to support the DDR Core Vocabulary, but in
reality I have only coded 11 of the properties, and provided data for a
handful of imaginary devices. This is sufficient to illustrate the
purpose of the API. There is no benefit from filling in more data.

I will not be working on this code for at least another month, so I have
delivered it for your consideration in its current state, without any
guarantees. It appears to be functioning as expected.
