Content services module

Provides abstraction around the way content is referred to in the system

Overview

Abstracts the process of reading and writing to files behind ContentReader and
ContentWriter objects, tied together by a ContentService that simplifies the
creation and management of these objects.

Content items are then referred to by their ContentId, which is a string
that represents the type of storage and a way of retrieving the content from
that storage location, eg

file:||content/folder/342/1233e342/filename.txt

Included is a Filesystem based implementation of ContentReader/Writer pair,
which stores content on the filesystem in a content/ directory.
