small updates to pathos doc for new defaults keywords, use of pipes;
fix: pyina.ez_map doesn't throw error due to getstr; added tests for ez_map;
moved getstr to all_launches; updated ez_map's default to pyina.mpi defaults;
updated ez_map to use mpi_pool and not parallel_map, similarly parallel_map2;
updated ez_map tmpdir to workdir, and nnodes to nodes; added tools.isoseconds;
moved cardealer_mapper to worker_pool, equalportion_mapper to scatter_gather;
mpi map's timeout is None unless has scheduler, or is explicitly set
