Change boolMatrix to subclass boolNDArray rather than be another Array<bool>. * boolMatrix.h: both boolMatrix and boolNDArray are Array<bool>, the first being simply 2 dimensional. We change this so that boolMatrix inherits from boolNDArray instead. * boolNDArray.cc, boolNDArray.h (boolNDArray::matrix_value): remove method since boolMatrix can be constructed from its parent. (boolNDArray::boolNDArray): remove constructor from boolMatrix * pr-output.cc, octave-value/ov-bool-mat.cc, octave-value/ov-bool-mat.h: replace calls to boolNDArray::matrix_value () with the boolMatrix constructor.
