CheckColumn plugin from the "Editable Grid" example on http://extjs.com/deploy/dev/examples/
The problem with it is that when a new record is added to the store, the corresponding field value 
is set to an empty string, instead of being set to false. Here's the fix for it.

= General suggestions:

• In the beginning, keep the current method naming to avoid confusion (and to be able to search on method names), but mark in the comments what's probably to be renamed.
• In most cases it would be hard to simplify things without a deep refactor. I may forget why I did something one way or another, but each time I decide "this should not be needed", sooner or later it proves needed in a specific scenario... Tests would be of great help here.

= Core

• Class-level configuration:
  • Netzke::Base.config and Netzke::GridPanel.config are decoupled.
• Example of usage:

mxgrn

module Netzke
  class FileUploader < FormPanel
    INITIAL_UPLOAD_FIELDS_NUMBER = 5

    # Extra javascripts
    def self.include_js
      [
        "#{File.dirname(__FILE__)}/file_uploader_extras/file_uploader.js"
      ]
    end

mxgrn

// in grid_panel_pre.js:

    // React on before edit event to set the recordId property in the editor
    this.on('beforeedit', function(e){
      e.grid.getColumnModel().getCellEditor(e.column, e.record).field.recordId = e.record.id;
    });

##### A million-dollar question: why the following isn't working?

class A
  def self.metamethod(name)
    define_method(name) do
      yield

#!/bin/sh
#
# This will abort "git commit" and remove the trailing whitespaces from the files to be committed.
# Simply repeating the last "git commit" command will do the commit then.
#
# Put this into .git/hooks/pre-commit, and chmod +x it.
