In vjcitn/benchOOM: benchmarking out-of-memory strategies for R

benchOOM

benchmarking out-of-memory strategies for R

Purpose is to allow comparison of timings of operations on NRxNC matrix: wr is write to store, ingFull is ingest from store, ing1K is ingest 1000 rows.

Also includes tentative work on exporting assay data from a RangedSummarizedExperiment as a DelayedArray with HDF5 back end.
