Pretty print Numpy histograms to the console

How does it work?
-----------------

Histoprint uses a mix of terminal color codes and unicode trickery (i.e.
combining characters) to plot overlaying histograms.

Examples
--------

Some examples::

    import numpy as np
    from histoprint import text_hist, print_hist

    A = np.random.randn(1000) - 2
    B = np.random.randn(1000)
    C = np.random.randn(1000) + 2
    D = np.random.randn(500) * 2

    # text_hist is a thin wrapper for numpy.histogram
    text_hist(
        B, bins=[-5, -3, -2, -1, -0.5, 0, 0.5, 1, 2, 3, 5], title="Variable bin widths"
    )

    histA = np.histogram(A, bins=15, range=(-5, 5))
    histB = np.histogram(B, bins=15, range=(-5, 5))
    histC = np.histogram(C, bins=15, range=(-5, 5))
    histD = np.histogram(D, bins=15, range=(-5, 5))
    histAll = ([histA[0], histB[0], histC[0], histD[0]], histA[1])

    # print_hist can be used to print multiple histograms at once
    # (or just to print a single one as returned by numpy.histogram)
    print_hist(histAll, title="Overlays", labels="ABCDE")
    print_hist(
        histAll,
        title="Stacks",
        stack=True,
        symbols="      ",
        bg_colors="rgbcmy",
        labels="ABCDE",
    )
    print_hist(
        histAll,
        title="Summaries",
        symbols=r"=|\/",
        fg_colors="0",
        bg_colors="0",
        labels=["AAAAAAAAAAAAAAAA", "B", "CCCCCCCCCCCCC", "D"],
        summary=True,
    )

The last example does not use terminal colors, so it can be copied as text::

Command line interface
----------------------

Histoprint also comes with a simple command line interface to create histograms
of tabulated data. It can read in text files or directly from STDIN::

    $ histoprint --help
    Usage: histoprint [OPTIONS] INFILE

      Read INFILE and print a histogram of the contained columns.

      INFILE can be '-', in which case the data is read from STDIN.

    Options:
      -b, --bins TEXT                 Number of bins or space-separated bin edges.
      -t, --title TEXT                Title of the histogram.
      --stack / --nostack             Stack the histograms.
      -s, --summary / -S, --nosummary
                                      Print summary statistics.
      -l, --label TEXT                Labels for the data, one for each column.
      --symbols TEXT                  Symbol cycle for multiple histograms.
                                      Choices & default: ' |=/\'

      --fg-colors TEXT                Colour cycle for foreground colours.
                                      Default: '0WWWWW', Choices:
                                      '0rgbcmykwRGBCMYKW'

      --bg-colors TEXT                Colour cycle for background colours.
                                      Default: 'K00000', Choices:
                                      '0rgbcmykwRGBCMYKW'

      --help                          Show this message and exit.
