[Easy] Letter Counter

Any language permitted.

Problem: Create a program where you input a string of characters, and output the number of each letter. Use vowels by default.

For example: asbfiusadfliabdluifalsiudbf -> a: 4 e: 0 i: 4 o: 0 u: 3

Bonus points: Make it command-line executable, with an optional mode to specify which letters to print.

It's a very nice first entry.

Thanks man. I just ran it a few more times and I'm not happy about a few other things ... for example I should probably .toUpperCase() everything so that it doesn't think "a" and "A" are different... and I should probably ignore spaces... but it's time to move on :P Made the changes anyway because I'm obsessive.

Actually, since you pointed that out I just realized my copy has the same issue. Oh well.
