Add table containing bibliographic references

@benoit.genot, we can add a table with these following columns:

• short citation reference (i.e. "Author et al. 2020" ; hyperlink to doir.org, HAL or webGR [if PhD thesis not on HAL])
• time step ("monthly", "daily", "hourly" and/or "< hourly")

Maybe we could replace the short citation reference by two columns in order to be able to sort the table by year. Where should we put the hyperlink in this case?

• authors
• year
