/* How parsing works
Parsing takes $Str, breaks it into blocks, and builds it into $Array.
Blocks start at the beginning of $Str, when the parser encounters a [, and after a tag has been closed.
This is all done in a loop.
EXPLANATION OF PARSER LOGIC
1) Find the next tag (regex)
1a) If there aren't any tags left, write everything remaining to a block and return (done parsing)
1b) If the next tag isn't where the pointer is, write everything up to there to a text block.
2) See if it's a [[wiki-link]] or an ordinary tag, and get the tag name
3) If it's not a wiki link:
3a) check it against the $this->ValidTags array to see if it's actually a tag and not [bullshit]
If it's [not a tag], just leave it as plaintext and move on
3b) Get the attribute, if it exists [name=attribute]
4) Move the pointer past the end of the tag
5) Find out where the tag closes (beginning of [/tag])
5a) Different for different types of tag. Some tags don't close, others are weird like [*]
5b) If it's a normal tag, it may have versions of itself nested inside - eg:
[quote=bob]*
[quote=joe]I am a redneck!**[/quote]
Me too!
***[/quote]
If we're at the position *, the first [/quote] tag is denoted by **.
However, our quote tag doesn't actually close there. We must perform
a loop which checks the number of opening [quote] tags, and make sure
they are all closed before we find our final [/quote] tag (***).
5c) Get the contents between [open] and [/close] and call it the block.
In many cases, this will be parsed itself later on, in a new parse() call.
5d) Move the pointer past the end of the [/close] tag.
6) Depending on what type of tag we're dealing with, create an array with the attribute and block.
In many cases, the block may be parsed here itself. Stick them in the $Array.
7) Increment array pointer, start again (past the end of the [/close] tag)
