You are to complete the `metric`

library started in the
lab exercise by expanding it to include the
conversions in the following table assigned by your instructor.
You must also expand the driver program from the lab exercise
to test these new conversions.

You should follow the pattern in the lab
exercise: first, *design* using OCD; then *code* your
design in C++ using stepwise translation; finally, test your modified
`metric`

library by adding to your driver program.

**Project #5.1**:
Expand the `metric`

library started in the exercise to include
the conversions in the following table:

Lengths | Weights |
---|---|

Inches to centimeters (1 inch = 2.54 cm) Yards to meters (1 yard = 0.9144 m) Miles to kilometers (1 mile = 1.609344 km) |
Ounces to grams (1 ounce = 28.349523 g) Pounds to kilograms (1 pound = 0.453592 kg) Tons to kilograms (1 ton = 907.18474 kg) |

Volumes | Areas |

Pints to liters (1 pint = 0.473163 l) Quarts to liters (1 quart = 0.946326 l) Gallons to liters (1 gallon = 3.785306 l) |
Square inches to square millimeters (1 sq. in. = 645.16 sq.mm) Square feet to square meters (1 sq. foot = 0.09290304 sq.m) Acres to square meters (1 Acre = 4.04686x10^3 sq.m). |

Each person is responsible for writing the necessary function prototypes, definitions, and documentation specifications. Each person should write up an OCD design for at least one of their functions.

Each *group*, though, should submit *exactly one* library,
bringing together all of the prototypes, definitions, and
documentations (in three separate files, of course).

Then one of the people in the group (under the close scrutiny of the other group members) should extend the driver from the lab exercise to test all of the functions with one input value.

The documentation file should indicate which group member was responsible for which functions. Only that group member will be penalized for any errors in that set of functions, or its documentation.
