Stanford EC301 potentiostat/galvanostate device.

Implements direct control of current and potential, potential step and cycle scans, and data acquisition. All hardware-triggered functionality relies on the trigger signal also being connected to the synchronous ADC input for filtering. Trigger pulses should therefore not be shorter than the data acquisition period (4 us - 1 ms depending on settings).

TODO:

• Error handling?
• Many of the attributes can have only certain values (see all the setter asserts in lib-maxiv-ec301). Write this somehow so that jive knows about the possible choices for each attribute.
