• Implemented particlecloud/utils.py:1.

Browse Source 
Added:

  - generate_particles_from_csv(...) plus common aliases
  - CSV parsing via column names: m/mass, v1..v3, p1..p3
  - conversion of string nan to numpy.nan
  - particles_ascii_table(...)
  - display_particles(...)

  Verification:

  - python3 -m py_compile particlecloud/utils.py passed.
  - python3 -m unittest discover found 0 tests because tests/test_utils.py is not present.
  - Runtime smoke test could not run because local NumPy fails to import due to an architecture
