Detect template for variable and text concatenation

[brainless]

Create a mechanism to detect the template for any variable and text concatenation:

• Check if text matches a simple template with a number and some words, like "42 comments", "16 hours ago", etc.
• The variables to be replaced should be either numbers or floats
• The allowed words should follow simple rules like "minutes", "hours"
• Create exhaustive tests for such patterns
• Check if we can create a template, like {count} comments, {count} hours ago from given content
• For any given content that fits a template syntax, return the syntax

Implement template detection in HTML node tree and mark matched nodes with template

• Create a CLI option --template to enable this stage separately
• When --template mode is ON do the following
• For each HTML node with content, check if we can find a template syntax for its content
• Print the template syntax instead of actual value where matches are found wherever we are printing the HTML node tree
