The 'Manipulating elements, 'Attribute references', and 'Inserting elements' sections of the documentation are reorganized. 'Manipulating elements' has been broken up into 4 sections:
* Attributes and styles
* Classes
* Transforming elements
* Altering the element tree
The 'Attribute references' section is folded into 'Attributes and styles', and the 'Inserting elements' section is folded into 'Altering the element tree'.
Some general information about positioning methods has been added/moved to a note at the beginning of the 'Transforming elements' section.
Many of the method descriptions in these sections have been edited for clarity, and a few typos have been fixed.
