/* Create layer tree from a simple layer tree description syntax.

 * Each index is either the first letter of the layer type or

 * a '(',')' to indicate the start/end of the child layers.

 * The aim of this function is to remove hard to read

 * layer tree creation code.

 * Example "c(c(c(tt)t))" would yield:

 *          c

 *          c

 *         / \
