Create a histogram

Method 1 - Using the histogram constructor

Syntax:

histogram<Type1, Type2, Type3,... TypeN>

Type1 .. TypeN correspond to the axis type of the N axes in the histogram

Example: If we want a 3D histogram of Axis1 of type int, Axis2 of type float and Axis3 of type std::string we would do it this way:

histogram<int, float, std::string> h;

And done.

Method 2 (TODO) - Using make_histogram()

There is an alternative to create the histogram directly from a GIL image view.

This should be the preferred over method-1 when creating histogram with GIL images, since it creates a histogram with axes configured to match the GIL image.

Also it is easier than method-1.

Syntax:

auto h = make_histogram(view(image));

where image could be a gray8_image_t/rgb8_image_t object read from source.
