UnitConstants (Manifold :: Science 2021.1.16 API)

```
public interface UnitConstants
```
A collection of commonly used SI units specified as standard abbreviations.
Import constants of this class individually like this:
```
   import static manifold.science.util.UnitConstants.m;
 
```
Or import all of them like this:
```
   import static manifold.science.util.UnitConstants.*;
 
```
Then use them to conveniently express Dimension values like this:
```
   Length distance = 90 mph * 25 min;
 
```
If you don't see the unit you're looking for here, make your own! Units are just types -- you can simply declare a constant of the unit type you want and use the constant as a unit qualifier:
```
   ForceUnit lbf = slug ft/s/s;  // pound-force unit 
```
Now you can make expressions using lbf force units!
```
   Force force = 72 lbf;
 
```
Note unlike floating point literals, these expressions retain the precision of literal decimal values.
