include Methods
# Creates a new mock with a +name+ (that will be used in error messages only)
# == Options:
# * <tt>:null_object</tt> - if true, the mock object acts as a forgiving null object allowing any message to be sent to it.

# This allows for comparing the mock to other objects that proxy
# such as ActiveRecords belongs_to proxy objects
# By making the other object run the comparison, we're sure the call gets delegated to the proxy target
# This is an unfortunate side effect from ActiveRecord, but this should be safe unless the RHS redefines == in a nonsensical manner
