modal_node_edit.module in Modal operations 7

Allows node editing, adding and deleting in modal window.

Reference: http://drupal.stackexchange.com/questions/21053/how-to-load-a-node-edit-...

@example Create links with the following href and class attributes (NID is the identifier of the node to edit, TYPE is the type of node to add): <a href="/modal/node/add/TYPE/nojs" class="ctools-use-modal">Create node and reload the page</a> or <a href="/modal/node/add/TYPE/nojs/0" class="ctools-use-modal">Create node without page reloading</a> or <a href="/modal/node/NID/edit/nojs" class="ctools-use-modal">Edit node and reload the page</a> or <a href="/modal/node/NID/edit/nojs/0" class="ctools-use-modal">Edit node without page reloading</a>. or <a href="/modal/node/NID/delete/nojs" class="ctools-use-modal">Delete node and reload the page</a> or <a href="/modal/node/NID/delete/nojs/0" class="ctools-use-modal">Delete node without page reloading</a>.

Ensure the page with such links executes the following functions (this is done in init code of modal.module): ctools_include('modal'); ctools_modal_add_js();
