**Make arbitrarily structured, arbitrary-dimension boxes and log-normal mocks.**

``powerbox`` is a pure-python code for creating density grids (or boxes) that have an
arbitrary two-point distribution (i.e. power spectrum). Primary motivations for creating
the code were the simple creation of log-normal mock galaxy distributions, but the
methodology can be used for other applications.

Features
--------
* Works in any number of dimensions.
* Really simple.
* Arbitrary isotropic power-spectra.
* Create Gaussian or Log-Normal fields
* Create discrete samples following the field, assuming it describes an over-density.
* Measure power spectra of output fields to ensure consistency.
* Seamlessly uses pyFFTW if available for ~double the speed.

Installation
------------
Simply ``pip install powerbox``. If you want ~2x speedup for large boxes, you can also
install ``pyfftw`` by doing ``pip install powerbox[all]``. If you are a conda user, you
may want to install ``numpy`` with conda first. If you want to develop ``powerbox``,
clone the repo and install with ``python -m pip install -e ".[dev]"``.
