Python parse tree definitions.
This is a very concrete parse tree; we need to keep every token and
even the comments and whitespace between tokens.
There's also a pattern matching implementation here.

Abstract base class for Node and Leaf.
This provides some default functionality and boilerplate using the
template pattern.
A node may be a subnode of at most one parent.

A pattern is a tree matching pattern.
It looks for a specific node type (token or symbol), and
optionally for a specific content.
This is an abstract base class. There are three concrete
subclasses:
- LeafPattern matches a single leaf node;
- NodePattern matches a single node (usually non-leaf);
- WildcardPattern matches a sequence of nodes of variable length.

Initializer. Takes optional type, content, and name.
The type, if given must be a token type (< 256). If not given,
this matches any *leaf* node; the content may still be required.
The content, if given, must be a string.
If a name is given, the matching node is stored in the results
dict under that key.

Initializer. Takes optional type, content, and name.
The type, if given, must be a symbol type (>= 256). If the
type is None this matches *any* single node (leaf or not),
except if content is not None, in which it only matches
non-leaf nodes that also match the content pattern.
The content, if not None, must be a sequence of Patterns that
must match the node's children exactly. If the content is
given, the type must not be None.
If a name is given, the matching node is stored in the results
dict under that key.

A wildcard pattern can match zero or more nodes.
This has all the flexibility needed to implement patterns like:
.* .+ .? .{m,n}
(a b c | d e | f)
(...)* (...)+ (...)? (...){m,n}
except it always uses non-greedy matching.

Initializer.
Args:
content: optional sequence of subsequences of patterns;
if absent, matches one node;
if present, each subsequence is an alternative [*]
min: optional minimum number of times to match, default 0
max: optional maximum number of times to match, default HUGE
name: optional name assigned to this match
[*] Thus, if content is [[a, b, c], [d, e], [f, g, h]] this is
equivalent to (a b c | d e | f g h); if content is None,
this is equivalent to '.' in regular expression terms.
The min and max parameters work as follows:
min=0, max=maxint: .*
min=1, max=maxint: .+
min=0, max=1: .?
min=1, max=1: .
If content is not None, replace the dot with the parenthesized
list of alternatives, e.g. (a b c | d e | f g h)*
