slicerator 0.9.0

Slicerator
==========

a lazy-loading, fancy-slicable iterable

Think of it like a generator that is "reusable" and has a length.

Example
-------

```
from slicerator import Slicerator

class MyLazyLoader:

def __getitem__(self, i):
# If a specific item is requested, load it and return it.
# Otherwise, return a lazy-loading Slicerator.
if isinstance(i, int):
# load thing number i
return thing
else:
return Slicerator(self, range(len(self)), len(self))[i]

def __len__(self):
# do stuff
return number_of_things

def __iter__(self):
return iter(self[:])

# Demo:
>>> a = MyLazyLoader()
>>> s1 = a[::2] # no data is loaded yet
>>> s2 = s1[1:] # no data is loaded yet
>>> some_data = s2[0]
```
