# Menu option 1 - Add a new recording of a species. This script allows the user to add a record to the speciesDetails file.
# The user is first asked if they would like to view the current contents of the file. Next they are prompted to enter the details of the record they wish to add, one at a time.
# Each variable is read in and validated as correct input. If the format is not correct the user will be informed and prompted to input the correct details. Once all 4 pieces of
# information have been input they are put together and shown to the user. If the user is happy they can save this record to the file, otherwise they can start again or return to
# the main menu. The script output is coloured using ANSI/VT100 escape sequences.

# Allowing user to view file before continuing. Using case statement for various options.
