// The FauxReader doesn't read from disk, but instead just makes up data for its
// points. The reader is constructed with a given bounding box and a given
// number of points.
//
// This reader knows about these fields (Dimensions):
// X,Y,Z - floats
// Time - uint64
// ReturnNumber (optional) - uint8
// NumberOfReturns (optional) - uint8
//
// It supports a few modes:
// - "random" generates points that are randomly distributed within the
// given bounding box
// - "constant" generates its points to always be at the minimum of the
// bounding box
// - "ramp" generates its points as a linear ramp from the minimum of the
// bbox to the maximum
// - "uniform" generates points that are uniformly distributed within the
// given bounding box
// - "normal" generates points that are normally distributed with a given
// mean and standard deviation in each of the XYZ dimensions
// In all these modes, however, the Time field is always set to the point
// number.
//
// ReturnNumber and NumberOfReturns are not included by default, but can be
// activated by passing a numeric value as "number_of_returns" to the
// reader constructor.
