use BOOST_CHECK_EQUAL for checking in tests
use BOOST_CHECK_EQUAL
use BOOST_CHECK_CLOSE instead of our own Compare function
provide a defaulted optional 'exact' switch to resize to force a resize of the PointBuffer even if current capcity is larger than the requested capacity
method to return chipper threshold
add method to return number of objects in cache
move cache testing into CacheFilterTeset
force a resize of the PointBuffer's capacity to the chipper's threshold when constructing the sequential filter
sequential filters.cache working for block-based reads
make IteratorBase class to contain common methods for filters.cache iterators
random iterator mostly working
account for situations where you're requesting the very first point
stop here, cache filter tests pass at least
don't create the one_point PointBuffer for every point, initialize RandomIterator with it
fix up table name
nuke the map every block read -- will make a map of these for inserts
fix up chpper to not create one_point every time through
reset dimension map every read()
keep a map of dimension maps for per-cached block lookups
