Module:Clade

--NOTE: this module contains functions for generating the table structure of the clade tree in two ways: -- (1) the original method was generated by a number of function calls from the template using Template:Invoke -- function p.openTable(frame) - creates wikitext code to open the HTML table -- function p.node(frame) - deals with the first node (|1,|label1) and creates wikitext for top row of the table -- function p.nodeN(frame) - deals with a sister nodes (|2-17), adding a row each time it is called -- function p.closeTable() - closes the HTML table -- (2) the revised method is called by the template with one Template:Invoke instruction; it has three functions: -- p.main(frame) - opens and closes table, loops through the children of node, main is invoked once and controls the rest, calling ... -- p.addTaxon(childNumber, nodeLeaf) - the nuts and bolts; code dealing with each child node -- p.addLabel(childNumber) - adds the label text
