Add support for channel #27

Closed MatthieuDartiailh closed 9 years ago

MatthieuDartiailh commented 9 years ago

This adds a 'channels' keyword to the parser. When declaring channel, for each channel one can declare the active ids ('ids') (which can be altered in the resource), whether or not the channel can be selected from within a command ('can_select') (ie Ch 1:VOLT:IMM is supported). If a device property can be used to select a channel it should be declared under the name 'select_channel'. This also adds support for concatenating multiple commands separated by a special character (';' by default and can be specified by declaring a 'delimiter' field. I also re-factored some things I needed in channel away from devices, they are now in component.py

I added some very basic tests also.

This is ready for review from my point of view. I will try to prepare another PR for sending error messages to an error queue and declare a dialog to query the last error.
