def evaluate(self, context):
"""
<Purpose>
Evaluates the wrapped code within a context.
<Arguments>
context: A global context to use when executing the code.
This should be a SafeDict object, but if a dict object is provided
it will automatically be converted to a SafeDict object.
<Exceptions>
Any that may be raised by the code that is being evaluated.
A RepyArgumentError exception will be raised if the provided context is not
a safe dictionary object or a ContextUnsafeError if the
context is a dict but cannot be converted into a SafeDict.
<Returns>
The context dictionary that was used during evaluation.
If the context was a dict object, this will be a new
SafeDict object. If the context was a SafeDict object,
then this will return the same context object.
