# The abstract base class for all CoffeeScript nodes.
# All nodes are implement a "compile_node" method, which performs the
# code generation for that node. To compile a node, call the "compile"
# method, which wraps "compile_node" in some extra smarts, to know when the
# generated code should be wrapped up in a closure. An options hash is passed
# and cloned throughout, containing messages from higher in the AST,
# information about the current scope, and indentation level.
