Calculates ecological information and biotic indices for diatoms in a sample. 
    It includes number/shape of chloroplasts diversity indices, size classes, ecological guilds, and multiple biotic indices.
    It outputs both a dataframe with all the results and plots of all the obtained data in a defined output folder.
    Sample data was taken from Nicolosi Gelis, Cochero & Gómez (2020, <doi:10.1016/j.ecolind.2019.105951>).
    The package uses the 'Diat.Barcode' database to calculate morphological and ecological information by Rimet & Couchez (2012, <doi:10.1051/kmae/2012018>),
    and the combined classification of guilds and size classes established by B-Béres et al. (2017, <doi:10.1016/j.ecolind.2017.07.007>).
    Current diatom-based biotic indices include the DES index by Descy (1979, <https://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&idt=PASCAL8060205402>),
