Subject: ss: Introduce SegmentStore plugin
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=26a6a7ebf26b8008ae4e8260f96d4e7c0bb6a1ed;p=deliverable%2Ftracecompass.git

ss: Introduce SegmentStore plugin

Unlike the State System, which assigns single states to attributes,
the Segment Store is a database interface for storing segments that
may overlap each other. It is closer in intent to a spatial database.

Just like state system backends, we provide an interface that can be
implemented in different ways. A first basic in-memory implementation
is provided.
