Our application is mining names from people using Twitter to login.

Twitter is providing full names in a single string.

Examples

```
1. "Froederick Frankenstien"
2. "Ludwig Van Beethoven"
3. "Anne Frank"

```

I'd like to split the string into only **two** vars (`first` and `last`) based on the first `" "` (space) found. 

```
Example    First Name    Last Name 
1          Froederick    Frankenstein
2          Ludwig        Van Beethoven
3          Anne          Frank

```

I'm familiar with `String#split` but I'm not sure how to only split once. The most Ruby-Way™ (elegant) answer will be accepted.
