Title Transform
===============

Write a function that transforms a string into [title case](http://en.wikipedia.org/wiki/Letter_case#Headings_and_publication_titles).

This mostly means capitalizing only every first letter of every word in the string. 

However, there are some non-obvious exceptions to title case which can't easily be hard-coded. Your function must accept, as a second argument, a set or list of words that should not be capitalized. 

Furthermore, the first word of every title should always have a capital leter. For example:
```python
exceptions = ['jumps', 'the', 'over']
titlecase('the quick brown fox jumps over the lazy dog', exceptions)
```
This should return:

		The Quick Brown Fox jumps over the Lazy Dog

An example from the Wikipedia page:
```python
	exceptions = ['are', 'is', 'in', 'your', 'my']
	titlecase('THE vitamins ARE IN my fresh CALIFORNIA raisins', exceptions)
```
Returns:

		The Vitamins are in my Fresh California Raisins
