Implements issue: #221 #236
Add standard guidance for stepBased iteration encoding.
stepBased
stepBased iteration encoding uses features of a storage, backend API or file format to encode time-varying data sets and attributes.
base
FORMAT: ADIOS
Instead of storing iterations (snapshots) in individual groups, we rely on internal capabilities of a data format to store updates/revisions.

Since this is a new iteration encoding that exists in parallel to existing iteration encodings, no conversion is necessary.
