the index mapping contains some relatively messy logic and the top-level bleve package only cares about a relatively small portion of this the motivation for this change is to codify the part that the top-level bleve package cares about into an interface then move all the details into its own package NOTE: the top-level bleve package still has hard dependency on the actual implementation (for now) because it must deserialize mappings from JSON and simply assumes it is this one instance. this is seen as OK for now, and this issue could be revisited in a future change. moving the logic into a separate package is seen as a simplification of top-level bleve, even though we still depend on the one particular implementation.
