  "Compute the bond orientational order diagram for the system of\n    particles.\n\n    The bond orientational order diagram (BOOD) is a way of studying the\n    average local environments experienced by particles. In a BOOD, a particle\n    and its nearest neighbors (determined by either a prespecified number of\n    neighbors or simply a cutoff distance) are treated as connected by a bond\n    joining their centers. All of the bonds in the system are then binned by\n    their azimuthal (:math:`\\theta`) and polar (:math:`\\phi`) angles to\n    indicate the location of a particle's neighbors relative to itself. The\n    distance between the particle and its neighbor is only important when\n    determining whether it is counted as a neighbor, but is not part of the\n    BOOD; as such, the BOOD can be viewed as a projection of all bonds onto the\n    unit sphere. The resulting 2D histogram provides insight into how particles\n    are situated relative to one-another in a system.\n\n    This class provides access to the classical BOOD as well as a few useful\n    variants. These variants can be accessed *via* the :code:`mode` arguments\n    to the :meth:`~BondOrder.compute` or :meth:`~BondOrder.accumulate`\n    methods. Available modes of calculation are:\n\n    * :code:`'bod'` (Bond Order Diagram, *default*):\n      This mode constructs the default BOOD, which is the 2D histogram\n      containing the number of bonds formed through each azimuthal\n      :math:`\\left( \\theta \\right)` and polar :math:`\\left( \\phi \\right)`\n      angle.\n\n    * :code:`'lbod'` (Local Bond Order Diagram):\n      In this mode, a particle's neighbors are rotated into the local frame of\n      the particle before the BOOD is calculated, *i.e.* the directions of\n      bonds are determined relative to the orientation of the particle rather\n      than relative to the global reference frame. An example of when this mode\n      would be useful is when a system is composed of multiple grain""s of the\n      same crystal; the normal BOOD would show twice as many peaks as expected,\n      but using this mode, the bonds would be superimposed.\n\n    * :code:`'obcd'` (Orientation Bond Correlation Diagram):\n      This mode aims to quantify the degree of orientational as well as\n      translational ordering. As a first step, the rotation that would align a\n      particle's neighbor with the particle is calculated. Then, the neighbor\n      is rotated **around the central particle** by that amount, which actually\n      changes the direction of the bond. One example of how this mode could be\n      useful is in identifying plastic crystals, which exhibit translational\n      but not orientational ordering. Normally, the BOOD for a plastic crystal\n      would exhibit clear structure since there is translational order, but\n      with this mode, the neighbor positions would actually be modified,\n      resulting in an isotropic (disordered) BOOD.\n\n    * :code:`'oocd'` (Orientation Orientation Correlation Diagram):\n      This mode is substantially different from the other modes. Rather than\n      compute the histogram of neighbor bonds, this mode instead computes a\n      histogram of the directors of neighboring particles, where the director\n      is defined as the basis vector :math:`\\hat{z}` rotated by the neighbor's\n      quaternion. The directors are then rotated into the central particle's\n      reference frame. This mode provides insight into the local orientational\n      environment of particles, indicating, on average, how a particle's\n      neighbors are oriented.\n\n    .. moduleauthor:: Erin Teich <erteich@umich.edu>\n\n    Args:\n        r_max (float):\n            Distance over which to calculate.\n        k (unsigned int):\n            Order parameter i.
