Split examples into separate markdown files, each containing a description, sample code, and a screenshot of the resulting xlsx document.

The script `generate.rb` is provided to actually generate the example documents by executing the sample code contained in the markdown files.

+This is a very basic example with a worksheet and two rows of data.
+
+## Code
+
+```ruby
+require 'axlsx'
+
+p = Axlsx::Package.new
+wb = p.workbook
+
+s = wb.styles
+wrap_text = s.add_style(alignment: { horizontal: :center, vertical: :center, wrap_text: true })
+
+wb.add_worksheet(name: 'Basic Worksheet') do |sheet|
+  rt = Axlsx::RichText.new
+  rt.add_run('I am bold, ', b: true)
+  rt.add_run('I am italic, ', i: true)
+  rt.add_run('I am strike', strike: true)
+  rt.add_run("\n")
+  rt.add_run('I am bold, italic and strike', b: true, i: true, strike: true)
+  rt.add_run("\n")
+  rt.add_run('I am style-less :D')
+
+  sheet.add_row [rt], style: wrap_text
+end
+
+p.serialize 'rich_text_example.xlsx'
