Update sm_1d_test to use Monitor Mixin

[chetan51]

It's currently using the old TemporalMemoryInspectMixin.

I think sm_1d_test may need an overhaul to incorporate the following:

• MonitorMixinBase or TemporalMemoryMonitorMixin; this would fix the broken code in issue Sensorimotor experiments broken #149
• SensorimotorExperimentRunner
  @chetan51 what do you think?

I'm not sure whether those tests are still valuable or not. Probably a question for @subutai, who I believe wrote some of them.

I'm fine if we delete it. I don't have any long term allegiance to research code. It's actually easier if we have fewer unit tests and only write those that help us debug the functionality.

Sounds good to me. I'll delete it in my next push for #149.
