Usage
Require:

If the value already has a unit, the unit will not be changed.
Example
Add 'px' to a number:
unitr(10); // -> "10px"
Add '%' to a number:
unitr(10, '%'); // -> "10%"
Attempt Add '%' to a value that is in px:
unitr('10px', '%'); // -> "10px"
Parse a value:
unitr.parse('10px'); // -> {value: 10, unit: 'px'}
