Apply a template to a string, and then recursively apply this template to each "child", as defined by a function.
- First parameter: Root of the tree
- Second parameter: Delimiter used to separate each application of the template; default is comma+space
- template: Template to apply to each node (first parameter is the node; depth and index are the tree coordinates, 1-based)
- children: Function mapping a parent to children (first parameter is the node; depth and index are the tree coordinates of the child, 1-based; empty result indicates no more children)
- start depth: What depth to consider the root to be at; default is 1
- skip root: Whether the root of the tree should be skipped; if set, the root's children have the start depth
