StreamCompressionModel
This type uses Huffman encoding to encode values in a lossless manner. When sending something like a 32-bit integer over the network, it is impractical to create a Huffman tree that encompasses every value the integer can take as it would require a tree with 2^32 leaves. To make this more practical, we lump values into a manageable number of power-of-two-sized buckets and then only code the bucket index with Huffman and code the position in the bucket using several raw bits corresponding to the size of the bucket.
The buckets are small, around 0, and become progressively larger as you move away from zero. As most data is deltas against predictions; we expect values to be small and expect most of the redundancy to be in the error's size and not in exactly which of the values of that size we end up hitting.
The context is as a sub-model that has its own statistics and uses its own Huffman tree. When using the context to read and write a specific value, the context must always be the same. The benefit of using multiple contexts is that it allows you to separate the statistics of things that have different expected distributions, which leads to more precise statistics, which again yields better compression. More contexts does, however, result in a marginal cost of a slightly larger model.
