### Simple
Simple notes are only intended to hold one paragraph with no advanced markup.
    (:note Title | Content:)

### Simple Hidden
the hidden note is a normal note that only shows the title of the note until you clicked on the title
    (:notehidden Title | Content:)

### Block
The block note allows as many wiki markup as you want in Title and Content

	(:noteblock <color=argument> <float=right(default)|left> <hidden=false(default)|true>:)
	Title
	(:notecontent:)
	Content
	(:noteblockend:)

The color argument can be:
* yellow(default)|blue|gray|pink|purple|green - predefined colors in script
* a hex color value like #cceecc
* a websafe colorname in capitals like YELLOW, BLACK ...

    (:noteblockfancy <float=right(default)|left>:)
    Content
    (:noteblockend:)
