At this small size (the 100 or so activities) it is unlikely to make much
sense to have indexes and such.  Simply reading the entire set of activities
into memory, adding new ones and writing out the simplest format possible is
probably as fast as any other implementation.

Indexes are useful to avoid reading unnecessary data from disk.  In this
case, you are going to have all of the information in memory already anyway
so you might as well save the space and avoid the indexes.
