Bivariate histogram plot from polar coordinates / position vectors.
Esentially, the coordinates are converted to cartesian coordinates and fed to
HISTOGRAM2. A polar-coordinate grid is then drawn in order to mimic a polar plot.
The properties and methods of this class are intended to mimic a polar plot like it
is created by POLARAXES and properties with the same name, such as 'ThetaDir', mimic
the behavior of a real POLARAXES. Note that this has limitations and might not work
flawlessly. Properties may be specified via Name-Value pairs during plot
construction or set post-hoc using dot-notation or set(obj, param, val). HISTOGRAM2
is called with the parameters {'DisplayStyle', 'tile', 'ShowEmptyBins', 'off',
'EdgeColor', 'none'}, which can be overridden by specifying the respective
Name-Value pairs during plot creation or by accessing the returned object's property
'Histogram'. Optional Name-Value pairs of this function support those specified
below and all Name-Value pairs as accepted by HISTOGRAM2.

Syntax:

histogram2Polar(theta, rho);
histogram2Polar(theta, rho, binWidth);
histogram2Polar(theta, rho, binWidth, Name, Value);
histogram2Polar(target, ___);
h = histogram2Polar(___);
