🚀 New/Added
- New method in `CAP` class to plot radar plot of cosine similarity (`CAP.caps2radar`).
- New method in `CAP` class to save CAPs as niftis without plotting (`CAP.caps2niftis`).
- Added new parameter to `CAP.caps2surf`, `fslr_giftis_dict`, to allow CAPs statistical maps that were
converted to giftis externally, using tools such as Connectome Workbench, to be plotted. This parameter only requires
the `CAP` class to be initialized.
