spbal: Spatially Balanced Sampling Algorithms

Encapsulates a number of spatially balanced sampling algorithms, namely, Balanced Acceptance Sampling (equal, unequal, seed point, panels), Halton frames (for discretizing a continuous resource), Halton Iterative Partitioning (equal probability), Simple Random Sampling, Dynamic Assignment Sampling and Doubly balanced Dynamic Assignment Sampling.
