Title: Implement a layer syntax

Layer system:
[ (nm|um|mm) Formula[<@Density>] [// (nm|um|mm) Formula<@Density>] // SubstrateFormaula[@]#x*y*z ]

layers can get grouped an repeated.
x,y are substrate dimensions (mm)
z is the substrate thickness (mm).

Example:
[( 1mm Fe[59] // 1mm Fe[58] )10 // Fe[57]#5*5*20 ]
10 times (1mm Fe[59]/1mm Fe[58]) on 20 mm Fe[57] with a 5x5 mm sq area.
