+BSON serialization and deserialization logic.
+Specifications taken from: http://bsonspec.org/#/specification
+The following types are unsupported, because for data exchange purposes, they're
+over-engineered:
+    0x06 (Undefined)
+    0x0b (Regex - Exactly which flavor do you want? Better let higher level
+        programmers make that decision.)
+    0x0c (DBPointer)
+    0x0d (JavaScript code)
+    0x0e (Symbol)
+    0x0f (JS w/ scope)
+    0x11 (MongoDB-specific timestamp)
+
+For binaries, only the default 0x0 type is supported.
