NestedStringParser

NestedStringParser takes a multi-line string, containing indented lines, and returns a Node object for each line, such that:

• node.parent returns the node for the most recent less-indented previous line
• node.children returns the nodes for all following more-indented lines, either up to end-of-string, or up to the next equally-indented or less-indented line
• node.value returns the stripped text of the line
• node.indent returns the length of the blank string for this line in the source string

See specs for some examples.

NestedStringParser is not terribly fussy about indentation ; any string that is indented more than a previous string will be assigned the previous string as parent. Use format to normalise indentation if your input is sloppy. Specs provide an example of sloppy indentation.
