Title: Explicit mapping

:warning: this PR braches off of the [error-transformer](https://github.com/github/Mantle/tree/error-transformer) branch and should be merged after #153 :warning:

This change set removes implicit mapping. Users need to invoke `MTLIdentityMappingForClass` to achieve the old behavior.

Fixes #149
