All tasks and their related components such as statuses are stored

for updating (moving tasks etc) and traversing the data. As tasks
are all linked through references, a transaction must be used to
get a consistent view on the data traversing through the
hierarchy/graph. Using an entity group in this way does limit the
writes to about 1/sec across the entire system, but in practice
that should not pose a problem as the application is read
dominated.
Tasks do not have a specific keyname, but use the auto-generated
numeric ids.
The hierarchy features in appengine for keys are not used to store
the hierachy of tasks, as it is very likely that the task
hierarchy changes.

"""
A record for every task. Tasks can form a hierarchy. Tasks have
single description. The title of a task is defined as the first
line of this description.
All tasks and their related components such as statuses are stored
in the same entity group, so transactions can be easily used both
for updating (moving tasks etc) and traversing the data. As tasks
are all linked through references, a transaction must be used to
get a consistent view on the data traversing through the
hierarchy/graph. Using an entity group in this way does limit the
writes to about 1/sec across the entire system, but in practice
that should not pose a problem as the application is read
dominated.
Tasks do not have a specific keyname, but use the auto-generated
numeric ids.
Some properties are replicated in the TaskIndex model. Each
Task has a corresponding TaskIndex, which is used to perform
some queries.
All functions specified in this class do not perform any RPC
calls, and can be used freely. Avoid accessing the properties
directly.
The logic that is used to compute the derived properties is
located in workers.py.
