Updated test instructions
The regex for pseudo elements :first-line, :first-letter, :before, :after should be case insensitive because these are also valid if capitalised
Tests were not running correctly. It is not a good idea to define a function inside a loop.
Updated the readme to be clear that the calculator does not process CSS Level 4 Selectors. https://github.com/keeganstreet/specificity/issues/5
Corrected bug where specificity is not calculated correctly for the pseudo-classes with brackets, :nth-child(), :nth-last-child(), :nth-of-type() and :nth-last-type(), if there is a plus or whitespace inside the brackets. https://github.com/keeganstreet/specificity/issues/5
