Created new tp.
Removed single unit test file in favor of each problem having its own file. Added format_phone_number TP and unit tests.
Added test prefix to all tests. Updated names to be more relevant.
Updated tests to use assertEqual where appropriate.
Pseudocoded.
Added function which uses regex to search for numbers and tests to validate. Currently not working.
