batch_erp_plot_components_by_indiv duplicate

[ybraverman]

batch_erp_plot_components_by_indiv and batch_erp_plot_components_by_indiv_GP exist - can you identify the meaningful differences between the two and condense into one - it also looks like "calc_si_by_indiv" is hard coded to run in one version - could you add some documentation for this file as to how "TSS" specific it is and how we'd need to modify it in the future to streamline for other paradigms?

Gerardo: Thinks one with initials is the latest version (used in late April) - could get rid of old version if Yael doesnt remember anything specific we'd need to keep there
