                         Changes in version 0.5                         

  - Changed from 'burst' name to 'group' name. This includes changing
    ind_burst -> s_group (single group) and multi_burst -> c_grouping
    (column grouping). Verbage has also been changed in all
    documentation.
  - Relative angle added to summary_sftrack, as well as fixing issue
    where absolute angle was calculating 180 from actual angle.
  - 'Active_group' were placed back at the column level. This means that
    any row level group does not have an active burst, but a column
    collection of bursts can define which of those groupings are
    'activated'.
  - Sort index returns and is an attribute of a column grouping. It is a
    factor that is recalculated everytime something in the data frame is
    changed like a subset or grouping is changed. This is to try to
    bring the sftrack grouping more inline with how dplyr::group_by
    works internally. You can access this with burst_labels (returns the
    factor) and burst_names (get just the levels()).
  - Plotting is more streamlined in both base plot and ggplot. A
    step_mode has been added for sftraj so you can choose to display the
    individual line segments. Although the default is to calculate the
    merged trajectories, which is must faster.
