Primitive logic to navigate from step to step; created 2 subvis

Created "main" vi.
Basic front panel organization: tabbed view for setting and shear;
power, proceed, preceed, and start over buttons.
Basic logic to navigate between steps and keep track of current state.

Created shell sub-vis: BallShear_DependencyCheck (check peripherals for
shut down / start up) and BallShear_PackageCheck (check for correct
placement of package at beginning of shear).
Created subvi-skeletons and placed them in the context of main project
Completed logic for main

"todos" added to subvis; subvis edited for necessary inputs / outputs
(ready for implementation)
image displaying with package and analyzed package
listbox populating with 1d array (for balls ids) and correlating with 2d
array (for ball coordinates) to select balls for shearing
TODO for main: change labels and disable/enable controls as necessary;
hide debugging indicators from GUI
