this is where the whole dialog structure is created.
A typical dialog looks like this:
===Start
Hello, welcome to Caldons tower of fun!
>caldon:Who is Caldon?
>name:Who are you?
>directions:How do I get into the tower?
topics start with = in pos 1 and can look like ===Start or =Treasure(5) (any number of ='s are ok as long as there is 1 in pos 1)
a number in parenthesis after the topic name is a "weight" for that entry, which is only used when you have multiple topics
with the same name and effects how frequently each is chosen.
weight is optional and defaults to 1.
you can have multiple topics with the same name, each gets a number, "subtopic",
when you reference that topic one of the multiple results will be chosen randomly
topics can only contain letters, numbers, underscores, and dashes, all other characters are stripped (letters are uppercased)
After the topic is the "say", this is what the npc says for this topic.
Replies start with > in position 1, and are followed by a target and a colon. The target is the "topic" this replay takes you to.
the reply follows the colon
You can also add commands, command start with a : in position 1
possible commands are:
:set varname=value
:if (a==b) then set varname=value
:if ( ((a==b) and (c>d)) or (e<=f)) then set varname=value
note that :if requires that the condition be in parenthesis.
The final structure of the dialog table will look like this:
npcself.dialog.vars (variable values for this npc)
npcself.dialog.text (the unprocessed dialog string)
npcself.dialog.
dlg[topic][subtopic].weight (the weight for this subtopic when chosen by random)
dlg[topic][subtopic].say (the text of the dialog that the npc says)
dlg[topic][subtopic].reply[replycount].target (what topic this reply will go to)
dlg[topic][subtopic].reply[replycount].text (the text of the reply)
dlg[topic][subtopic].cmnd[cmndcount].cmnd (SET or IF)
dlg[topic][subtopic].cmnd[cmndcount].cmnd=SET
dlg[topic][subtopic].cmnd[cmndcount].varname (variable name to be set)
dlg[topic][subtopic].cmnd[cmndcount].varval (value to set the variable to)
dlg[topic][subtopic].cmnd[cmndcount].cmnd=IF
dlg[topic][subtopic].cmnd[cmndcount].condstr (the condition string, a==b etc, must be in parens)
dlg[topic][subtopic].cmnd[cmndcount].ifcmnd.cmnd (SET for now, GOTO later?, entire structure of subcommand will be here)
dlg[topic][subtopic].gototopic.topic (used by goto to indicate which topic to goto)
dlg[topic][subtopic].gototopic.count (goto depth count, used to ensure you can not get into an infinite goto loop)

this is the other side of load_dialog_from_string. dialog_to_formspec turns a dialog table into
a formspec with the say text and reply list.
this is when variables are substituted, functions executed, and commands run.
a quick note on weight. the weight number for each subtopic is the maximum weight for that topic.
So, for example, if you have three treasure topics like this
=Treasure(2)
=Treasure(4)
=Treasure(7)
you will get weights like this:
dlg[Treasure][1].weight=2
dlg[Treasure][2].weight=6 (2+4=6)
dlg[Treasure][3].weight=13 (6+7=13)
this means we can just roll a random number between 1 and 13,
then select the first subtopic for which our random number is less than or equal to its weight.

Grouping
--]]
--this function will go through a string and build a list that tells what order
--to process parenthesis (or any other open close delimiter) in.
--example:
--12345678901234
--((3*(21+2))/4)
--list[1].open=5 close=10
--list[2].open=2 close=11
--list[3].open=1 close=14
--note that if you pass this txt that has bad syntax, it will not throw an error, but instead stop processing and return the list up to that point.
--list[].open and close are inclusive. it includes the delimeter
--list[].opene and closee are exclusive. it does NOT include the delimiter
--so in the above example:
--list[1].opene=6 close=9
--list[2].opene=3 close=10
--list[3].opene=2 close=13
--
--if you pass funcname then only entries that start with funcname( are returned in the final list
--for funcname we can NOT just pass funcname( as the opendelim, because if we did, grouping
--would NOT take into account other functions or parenthesis. example:
--add(goodnums,calc(@[x]@+1)) <- we need add to recognize the calc function or it will get the wrong close delimiter
