Get the UB matrix corresponding to the real space edge vectors a,b,c.
The inverse of the matrix with vectors a,b,c as rows will be stored in UB.
@param UB A 3x3 matrix that will be set to the UB matrix.
@param a_dir The real space edge vector for side a of the unit cell
@param b_dir The real space edge vector for side b of the unit cell
@param c_dir The real space edge vector for side c of the unit cell
@return true if UB was set to the new matrix and false if UB could not be
set since the matrix with a,b,c as rows could not be inverted.
