This implements the node core assert API as an Unexpected facade.
A great deal of emphasis was placed on compatibility and this module aims to be a drop-in replacement. It was developed against the node 4.7.3 test suite in core which it passes with the exception of the following:
- circular references are not supported
- deepEqual() not throwing on comparisons of:
- "a" to {0:'a'} (supported for Arrays)
- mismatching prototypes
