CommandGroup to approach the tote, latch the tote

[toastertaster]

WPILib has a CommandGroup class that performs a series of individual Commands. What we desire here is to show that we can drive forward (perhaps until the camera sees the tote centered as in #92 ) and then latch onto the tote.

See https://chantilly612code.github.io/612-2015/class_command_group.html for documentation

93.6% sure this will be done with auto align. Therefore closing this due to redundancy.
