For the case of Clojure and other Lisp syntax highlighting, it is
necessary to create huge regexps consisting of hundreds of symbols with
the pipe (|) character. To make things more difficult, these Lisp
symbols sometimes consists of special characters that are themselves
part of special regexp characters like '*'. In addition to being
difficult to maintain, it's performance is suboptimal.
This patch introduces a new predicate to perform 'source' matching in
amortized constant time. This is accomplished by compiling a hash table
on the first use.
Add support for default start and end row when omitted in the
query:iter_captures and query:iter_matches functions.
When the start and end row values are omitted, the values of the given
node is used. The end row value is incremented by 1 to include the node end
row in the match.
Updated tests and docs accordingly.
Implement the LanguageTree structure to enable language injection.
This is done be removing the old Parser metatable and replacing by the
new structure, with the same API (almost).
Some noticeable differences :
- `parser:parse()` now returns a table of trees
- There is no incremental parsing for child (injected) languages

- Describe query components (capture, match, pattern). Not
well-described in tree-sitter documentation.
- Describe Query() object. Not actually described anywhere in
documenation.
