/*
This function loops through all the text inputs on a page and stores their default values.
When a text input is brought into focus, its current value is checked against its default value.
If they are the same, the value is cleared.

This allows you to add placeholder text to inputs (recommended for accessibility) but users don't have to manually delete the placeholder text.
