/** @brief Changes the shape of a multi-dimensional array without copying the data.
The function is an advanced version of cvReshape that can work with multi-dimensional arrays as
well (though it can work with ordinary images and matrices) and change the number of dimensions.
Below are the two samples from the cvReshape description rewritten using cvReshapeMatND:
@code
IplImage* color_img = cvCreateImage(cvSize(320,240), IPL_DEPTH_8U, 3);
IplImage gray_img_hdr, *gray_img;
gray_img = (IplImage*)cvReshapeMatND(color_img, sizeof(gray_img_hdr), &gray_img_hdr, 1, 0, 0);
...
int size[] = { 2, 2, 2 };
CvMatND* mat = cvCreateMatND(3, size, CV_32F);
CvMat row_header, *row;
row = (CvMat*)cvReshapeMatND(mat, sizeof(row_header), &row_header, 0, 1, 0);
@endcode
In C, the header file for this function includes a convenient macro cvReshapeND that does away with
the sizeof_header parameter. So, the lines containing the call to cvReshapeMatND in the examples
may be replaced as follow:
@code
gray_img = (IplImage*)cvReshapeND(color_img, &gray_img_hdr, 1, 0, 0);
...
row = (CvMat*)cvReshapeND(mat, &row_header, 0, 1, 0);
@endcode
@param arr Input array
@param sizeof_header Size of output header to distinguish between IplImage, CvMat and CvMatND
output headers
@param header Output header to be filled
@param new_cn New number of channels. new_cn = 0 means that the number of channels remains
unchanged.
@param new_dims New number of dimensions. new_dims = 0 means that the number of dimensions
remains the same.
@param new_sizes Array of new dimension sizes. Only new_dims-1 values are used, because the
total number of elements must remain the same. Thus, if new_dims = 1, new_sizes array is not
used.

/** @brief Opens file storage for reading or writing data.
The function opens file storage for reading or writing data. In the latter case, a new file is
created or an existing file is rewritten. The type of the read or written file is determined by the
filename extension: .xml for XML, .yml or .yaml for YAML and .json for JSON.
At the same time, it also supports adding parameters like "example.xml?base64".
The function returns a pointer to the CvFileStorage structure.
If the file cannot be opened then the function returns NULL.

@param memstorage Memory storage used for temporary data and for
: storing dynamic structures, such as CvSeq or CvGraph . If it is NULL, a temporary memory

@param flags Can be one of the following:

@param name Name of the written structure. The structure can be accessed by this name when the

@param struct_flags A combination one of the following values:
- **CV_NODE_SEQ** the written structure is a sequence (see discussion of CvFileStorage ),
that is, its elements do not have a name.
- **CV_NODE_MAP** the written structure is a map (see discussion of CvFileStorage ), that
is, all its elements have names.
One and only one of the two above flags must be specified
- **CV_NODE_FLOW** the optional flag that makes sense only for YAML streams. It means that
the structure is written as a flow (not as a block), which is more compact. It is
recommended to use this flag for structures or arrays whose elements are all scalars.
@param type_name Optional parameter - the object type name. In
case of XML it is written as a type_id attribute of the structure opening tag. In the case of
YAML it is written after a colon following the structure name (see the example in
CvFileStorage description). In case of JSON it is written as a name/value pair.
Mainly it is used with user objects. When the storage is read, the
encoded type name is used to determine the object type (see CvTypeInfo and cvFindType ).

- **dt** description of the sequence elements.
- **recursive** if the attribute is present and is not equal to "0" or "false", the whole
tree of sequences (contours) is stored.
-# CvGraph
- **header_dt** description of user fields of the graph header that follows CvGraph;
- **vertex_dt** description of user fields of graph vertices
- **edge_dt** description of user fields of graph edges (note that the edge weight is
