Get the currencies of numbers within a string.

Description

The currency of a number is defined as the character coming before the number in the string. If nothing comes before (i.e. if the number is the first thing in the string), the currency is the empty string, similarly the currency can be a space, comma or any manner of thing.

• get_currency takes a string and returns the currency of the first number therein. It is vectorized over string.

• get_currencies takes a string and returns the currencies of all of the numbers within that string. It is not vectorized.
