# This class is used to represent a block label which can be constructed using various components.
# It handles initialization using a hash and provides a method to create a label string.
#
# Example Usage:
# block = {
#   filename: 'example.md',
#   headings: ['Header1', 'Header2'],
#   menu_blocks_with_docname: true,
#   menu_blocks_with_headings: false,
#   title: 'Sample Title',
#   body: 'Sample Body',
#   text: 'Sample Text'
# }
# label_obj = BlockLabel.new(block)
# label_str = label_obj.make
#
