Convert form XYZ coordinate to YBC format (LRA)

Convert form XYZ coordinate to YBC format (LRA).

XYZ2YBC convert form XYZ coordinate to YBC format (LRA)
XYZ2YBC(X,Y,Z) convert the X,Y,Z values to Y,B,C values. assuming the bend radius is zero. the size of X,Y and Z must be the same.

XYZ2YBC(X,Y,Z,R) where R is the bend radius. convert the X,Y,Z values to
Y,B,C values, taking in to account the bend radius R.

XYZ2YBC(X,Y,Z,R) where R is the bend radius matrix for each bend. convert the X,Y,Z values to Y,B,C values, taking in to account the bend radius R for each bend. size of R must be less than the number of XYZ points by 2.

returns Y length between bends, B rotation between bends in radius,+ for clockwise and - for anticlockwise, C angle of bend in radius.
