# Checks that given_value is in range of correct_value +/- tolerance.
# Tolerance can be an absolute value or a percentage of the correct value
# (see examples with tolerances below).
# Outputs suitable message to stdout if it's not in range.
#
# A verbose option, -v, may be used as the LAST argument
#
# e.g.
# foo: 0.0298 = 0.03 +/- 5%
# _within_tolerance "foo" 0.0298 0.03 5%
#
# foo: 0.0298 = 0.03 +/- 0.01
# _within_tolerance "foo" 0.0298 0.03 0.01
#
# foo: 0.0298 = 0.03 -0.01 +0.002
# _within_tolerance "foo" 0.0298 0.03 0.01 0.002

# foo: verbose output of 0.0298 = 0.03 +/- 5%
