A variation of the textarea component that resizes as you type.
This is using the Autosize libarary.
Using this component will make each textarea component autogrow by default.
This component relies on the Textarea component.
This component assumes that there is no other component that has a function with this name:
If your theme already has this exact function name in use, you should copy the contents of this function and put them in the already existing one. (every function name in php has to be unique).
