Preprocesser requires one function to use: preprocess. Takes Tokens and gives back Units. A unit is a tree of tokens, where each unit is a node in that tree. A unit has a "root" token (value of node) and an "expansion" (children of node) where the root is some preprocesser token (such as a reference or USE call) and the expansion is the tokens it yields. In the case of a USE call this is the tokens of the file it includes, in the case of a reference it's the tokens of the constant it refers to. This means that the leaves of the tree of units are the completely preprocessed/expanded form of the source code. The function has many working components, which may need to be extracted. In particular, the function ensures we don't include a source twice through a hash map and that constants are not redefined in inner include scopes if they're already defined in outer scopes (i.e. if compiling a.asm which defines constant N, then include b.asm which defines constant N, then N uses the definition of a.asm rather than b.asm). I need to make a spec for this.
