''' Allows the user to import Cisco configuration files.

Adds the "File:Import:Import Cisco Configuration" menu item. The plugin will:

1)  Create a new node, under the current node, where the configuration will be
    written. This node will typically have references to several sections (see below).

2)  Create sections (child nodes) for the indented blocks present in the original
    config file. These child nodes will have sub-nodes grouping similar blocks (e.g.
    there will be an 'interface' child node, with as many sub-nodes as there are real
    interfaces in the configuration file).

3)  Create sections for the custom keywords specified in the customBlocks[] list in
    importCiscoConfig(). You can modify this list to specify different keywords. DO
    NOT put keywords that are followed by indented blocks (these are taken care of by
    point 2 above). The negated form of the keywords (for example, if the keyword is
    'service', the negated form is 'no service') is also included in the sections.

4)  Not display consecutive empty comment lines (lines with only a '!').

All created sections are alphabetically ordered.
