/**
  * This is the parser for the SilverStripe template language. It gets called on a string and uses a php-peg parser
  * to match that string against the language structure, building up the PHP code to execute that structure as it
  * parses
  *
  * The $result array that is built up as part of the parsing (see thirdparty/php-peg/README.md for more on how
  * parsers build results) has one special member, 'php', which contains the php equivalent of that part of the
  * template tree.
  *
  * Some match rules generate alternate php, or other variations, so check the per-match documentation too.
  *
  * Terms used:
  *
  * Marked: A string or lookup in the template that has been explictly marked as such - lookups by prepending with
  * "$" (like $Foo.Bar), strings by wrapping with single or double quotes ('Foo' or "Foo")
  *
  * Bare: The opposite of marked. An argument that has to has it's type inferred by usage and 2.4 defaults.
  *
  * Example of using a bare argument for a loop block: <% loop Foo %>
  *
  * Block: One of two SS template structures. The special characters "<%" and "%>" are used to wrap the opening and
  * (required or forbidden depending on which block exactly) closing block marks.
  *
  * Open Block: An SS template block that doesn't wrap any content or have a closing end tag (in fact, a closing end
  * tag is forbidden)
  *
  * Closed Block: An SS template block that wraps content, and requires a counterpart <% end_blockname %> tag
  *
  * Angle Bracket: angle brackets "<" and ">" are used to eat whitespace between template elements
  * N: eats white space including newlines (using in legacy _t support)
