Jonathan A. Sternberg 728bdd6562 Fix the derivative and others time ranges for aggregate data 
The derivative function and others similar to it would preload
themselves with data so that the first interval would be the start of
the time range. That meant reading data outside of the time range.

One change to the shard mapper back in v1.4.0 caused the shard mapper to
constrict queries to the intervals given to the shard mapper. This was
correct because the shard mapper can only deal with times it has mapped,
but this broke the functionality of looking back into the past for
the derivative and other functions that used that functionality.

The compiler has been updated with an additional attribute that records
how many intervals in the past will need to be read so that the shard
mapper can include extra times that it may not necessarily read from,
but may be queried because of the above described functionality.
