This is the Part II of Multiplying numbers as strings.

TODO

Multiply two numbers! Simple!

Rules

1. The arguments are passed as strings.
2. The numbers will be very large
3. The arguments can be negative, in decimals, and might have leading and trailing zeros. e.g. "-01.300"
4. Answer should be returned as string
5. The returned answer should not have leading or trailing zeroes (when applicable) e.g. "0123" and "1.100" are wrong, they should be "123" and "1.1"
6. Zero should not be signed and "-0.0" should be simply returned as "0".
