"Camel Case" is a way of writing a phrase without the use of spaces, but which allows its individual words to be read separately. Most of the phrase is rendered in lowercase, but the first letter of each word is rendered in uppercase. For example, the phrase "user account info" would be rendered in camel case as "UserAccountInfo".

Write a method called toCamelCase that takes as an argument phrase and returns that phrase may contain any number of words. You may assume that the phrase contains no digits or punctuation, and that words are separated by single spaces (no bad input will be given).
