# 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% 

# _within_tolerance "foo" 0.0298 0.03 5% -v
