# Bash function to prompt terminal user for yes|no
# Author: Oscar Kramer
#
# If interactive shell, prompts user for confirmation considering optional default (Y|N) specified.
# The default is returned if <enter> is typed in lieu of a y|n character. The prompt is appended with
# " [Y|n]:" or " [y|N]:" depending on default provided.
#
# If not interactive, returns answerYes=1, answerNo=0
# Returns boolean
