A decorator for caching properties in classes.

Why?

• Makes caching of time or computational expensive properties quick and easy.
• Because I got tired of copy/pasting this code from non-web project to non-web project.
• I needed something really simple that worked in Python 2 and 3. (Python 3.8 added a version of this decorator as @functools.cached_property.)

How to use it

Let's define a class with an expensive property. Every time you stay there the price goes up by $50!

```python class Monopoly:

def __init__(self):
    self.boardwalk_price = 500

@property
def boardwalk(self):
    # In reality, this might represent a database call or time
    # intensive task...
