% function y = zeroTo360(x,unit)
%
% Purpose: This function reduces an angle to the range of 0 - 360 degrees
%          or 0 - 2*pi radians.
%
% Inputs:   x    - Angle to be reduced, may be an array of angles
%           unit - Boolean, 1 for radians, 0 for degrees, defaults to
%                  degrees [OPTIONAL]
%
% Output:   y    - Reduced angle
