Intercepts - Powerful Feature to Augment Code/State

Intercepts provide a simple and efficient means for augmenting function calls as well as local and global state during testing.  You can think of like like meck but with almost **zero** overhead.  They greatly increase the number of scenarios which can be tested by riak test.  

See the [Intercepts README section] [readme] for all the details.
