ToArray doesn't respect slices

[Ykid]

Thank you for providing such a nice library. I've found some cases which might potentially be buggy. Could you help take a look?

Here is the test case

import Matft

final class MatftTest: XCTestCase {
    func testMatftCase1() throws {
        let a = MfArray([], mftype: .Float)
    }

    func testMatftCase2() throws {
        let b = MfArray([], mftype: .Float, shape: [0])
    }

    func testMatftCase3() throws {
        let a = MfArray([
            [1,2,3],
            [4,5,6]
        ], mftype: .Float)
        XCTAssertEqual(a[1], MfArray([4,5,6], mftype: .Float))
        XCTAssertEqual(a[1].toArray() as! [Float], [4.0,5,6])  //XCTAssertEqual failed: ("[1.0, 2.0, 3.0, 4.0, 5.0, 6.0]") is not equal to ("[4.0, 5.0, 6.0]")
    }
}

Thanks!
