Given the n-D transpose pattern 'transp', return true if 'dim0' and 'dim1' should be transposed with each other within the context of their 2D transposition slice.
Example 1: dim0 = 0, dim1 = 2, transp = [2, 1, 0] Return true: dim0 and dim1 are transposed within the context of their 2D transposition slice ([1, 0]).
Example 2: dim0 = 0, dim1 = 1, transp = [2, 1, 0] Return true: dim0 and dim1 are transposed within the context of their 2D transposition slice ([1, 0]). Paradoxically, note how dim1 (1) is not transposed within the full context of the transposition.
Example 3: dim0 = 0, dim1 = 1, transp = [2, 0, 1] Return false: dim0 and dim1 are not transposed within the context of their 2D transposition slice ([0, 1]). Paradoxically, note how dim0 (0) and dim1 (1) are transposed within the full context of the of the transposition.
