FoundationDB/sql-layer — pull request #1409 by geophile (2014-08-15 20:45:42+00:00)
Title: Refactoring in preparation for integration with geophile. The goal was

to do the binding of the z-value in AbstractStore, instead of deeper
in PersistitIndexRowBuffer. This sets the stage for handling non-point
spatial objects which give rise to multiple z-values, each represented
by an index row.
