URI Value types

type	info	format	example
vector	x,y,z	comma-separated	#pos=1,2,3
string	color	FFFFFF (hex)	#fog=5m,FFAACC
string			#q=-sun
int		[-]x[xxxxx]	#price:>=100
float		[-]x[.xxxx] (ieee)	#prio=-20
array	mixed	|-separated	#pos=0,0,0

rule for thumb: type-limitations will piggyback JSON limitations (IEEE floatsize e.g.)

Url parser (the gist of it)

1. fragment URI starts with #
2. fragments are split by &
3. fragment-values are urlencoded ( becomes + and so on)
4. = is used to indicate fragmentvalues
5. | is used to indicate multiple/fallback values
6. hex colors are detected using regex /^#([A-Fa-f0-9]{6}|[A-Fa-f0-9]{3})$/
7. integers are detected using regex /^[0-9]+$/
8. floats are detected using regex /^[0-9]+\.[0-9]+$/
9. , is used to detect vector 1D/2D/3D values like x[,y[,z]]
10. anything else will be treated as string-value
11. last resort: inappropriate string values will be converted using parseInt/parseFloat
