/*Description:
Remove the parentheses

In this kata you are given a string for example:

"example(unwanted thing)example"

Your task is to remove everything inside the parentheses as well as the parentheses themselves.

The example above would return:

"exampleexample"

Notes

    Other than parentheses only letters and spaces can occur in the string.
    Don't worry about other brackets like "[]" and "{}" as these will never appear.
    There can be multiple parentheses.
    The parentheses can be nested.
