Hi @orbeckst, @jeremyleung521, @amruthesht, @HeydenLabASU,

This PR adds a Helix Analysis widget that uses MDAnalysis.analysis.helix_analysis.HELANAL and uses the Helix analysis example as reference.

This widget too supports batching, parallelization and plots for local_twists, local_nres_per_turn, local_bends, local_heights and local_screw_angles that users can select from.

Here is an example showing the average local twists in both serial and batch mode:

Thanks
