// builds  structure representing links nested at various levels
// elements in toc-entry class appear in the structure. Other attributes are used to the entry:
// * data-toc-level - the nesting level of this entry
// * data-toc-href - the href attribute of the generaetd link
// * data-toc-text - the text of the generated link
// Links are placed into the structure in the order they appear in the document.
// Nesting levels are not skipped. If you jump from level 0 to level 2, an intermediate
//  at level 1 will be interposed.
// The structure is decorated with classes so as to work as a bootstrap TOC.
