/**
 * matchRecursiveRegExp
 *
 * (c) 2007 Steven Levithan <stevenlevithan.com>
 * MIT License
 *
 * Accepts a string to search, a left and right format delimiter
 * as regex patterns, and optional regex flags. Returns an array
 * of matches, allowing nested instances of left/right delimiters.
 * Use the "g" flag to return all matches, otherwise only the
 * first is returned. Be careful to ensure that the left and
 * right format delimiters produce mutually exclusive matches.
 * Backreferences are not supported within the right delimiter
 * due to how it is internally combined with the left delimiter.
 * When matching strings whose format delimiters are unbalanced
 * to the left or right, the output is intentionally as a
 * conventional regex library with recursion support would
 * produce, e.g. "<<x>" and "<x>>" both produce ["x"] when using
 * "<" and ">" as the delimiters (both strings contain a single,
 * balanced instance of "<x>").
 *
 * examples:
 * matchRecursiveRegExp("test", "\\(", "\\)")
 * returns: []
 * matchRecursiveRegExp("<t<<e>><s>>t<>", "<", ">", "g")
 * returns: ["t<<e>><s>", ""]
 * matchRecursiveRegExp("<div id=\"x\">test</div>", "<div\\b[^>]*>", "</div>", "gi")
 * returns: ["test"]

// The blocktype is the most important concept within the block API. It defines
// all aspects of the block configuration and its interfaces, including `edit`
// and `save`. The transforms specification allows converting one blocktype to
// another through formulas defined by either the source or the destination.
// Switching a blocktype is to be considered a one-way operation implying a
// transformation in the opposite way has to be handled explicitly.
 // The block tree is composed of a collection of block nodes. Blocks contained
// within other blocks are called inner blocks. An important design
// consideration is that inner blocks are -- conceptually -- not part of the
// territory established by the parent block that contains them.
//
// This has multiple practical implications: when parsing, we can safely dispose
// of any block boundary found within a block from the innerHTML property when
// transfering to state. Not doing so would have a compounding effect on memory
// and uncertainty over the source of truth. This can be illustrated in how,
// given a tree of `n` nested blocks, the entry node would have to contain the
// actual content of each block while each subsequent block node in the state
// tree would replicate the entire chain `n-1`, meaning the extreme end node
// would have been replicated `n` times as the tree is traversed and would
// generate uncertainty as to which one is to hold the current value of the
// block. For composition, it also means inner blocks can effectively be child
// components whose mechanisms can be shielded from the `edit` implementation
// and just passed along.



 // While block transformations account for a specific surface of the API, there
// are also raw transformations which handle arbitrary sources not made out of
// blocks but producing block basaed on various heursitics. This includes
// pasting rich text or HTML data.

 // The process of serialization aims to deflate the internal memory of the block
// editor and its state representation back into an HTML valid string. This
// process restores the document integrity and inserts invisible delimiters
// around each block with HTML comment boundaries which can contain any extra
// attributes needed to operate with the block later on.

 // Validation is the process of comparing a block source with its output before
// there is any user input or interaction with a block. When this operation
// fails -- for whatever reason -- the block is to be considered invalid. As
// part of validating a block the system will attempt to run the source against
// any provided deprecation definitions.
//
// Worth emphasizing that validation is not a case of whether the markup is
// merely HTML spec-compliant but about how the editor knows to create such
// markup and that its inability to create an identical result can be a strong
// indicator of potential data loss (the invalidation is then a protective
// measure).
//
// The invalidation process can also be deconstructed in phases: 1) validate the
// block exists; 2) validate the source matches the output; 3) validate the
// source matches deprecated outputs; 4) work through the significance of
// differences. These are stacked in a way that favors performance and optimizes
// for the majority of cases. That is to say, the evaluation logic can become
// more sophisticated the further down it goes in the process as the cost is
// accounted for. The first logic checks have to be extremely efficient since
// they will be run for all valid and invalid blocks alike. However, once a
// block is detected as invalid -- failing the three first steps -- it is
// adequate to spend more time determining validity before throwing a conflict.


 // Blocks are inherently indifferent about where the data they operate with ends
// up being saved. For example, all blocks can have a static and dynamic aspect
// to them depending on the needs. The static nature of a block is the `save()`
// definition that is meant to be serialized into HTML and which can be left
// void. Any block can also register a `render_callback` on the server, which
// makes its output dynamic either in part or in its totality.
//
// Child blocks are defined as a relationship that builds on top of the inner
// blocks mechanism. A child block is a block node of a particular type that can
// only exist within the inner block boundaries of a specific parent type. This
// allows block authors to compose specific blocks that are not meant to be used
// outside of a specified parent block context. Thus, child blocks extend the
// concept of inner blocks to support a more direct relationship between sets of
// blocks. The addition of parent–child would be a subset of the inner block
// functionality under the premise that certain blocks only make sense as
// children of another block.


 // Templates are, in a general sense, a basic collection of block nodes with any
// given set of predefined attributes that are supplied as the initial state of
// an inner blocks group. These nodes can, in turn, contain any number of nested
// blocks within their definition. Templates allow both to specify a default
// state for an editor session or a default set of blocks for any inner block
// implementation within a specific block.
