Assert/IF against variables using template strings

Now you can create assertions and IF conditions against template strings. Most notably, template strings can include references to variables.

Examples:

1. Here we assert that the inner text of an <h3> element has the expected text contained in the existing variable expected_value. The {{@variableName}} syntax tells mabl to substitute the value of the variable here.

2. Step number 3 is an example of an IF conditional using a variable substitution for {{@app.url}}. Because the href value also has a / at the end, the pattern we use for the expected value is {{@app.url}}/.

You can combine these variable substitutions with any other text, or even combine multiple variables together like this: {{@first_name}} {{@last_name}}

You can now assert that one variable is equal to another, by selecting a variable as the source for the comparison, and using a template string to compare to a variable value.
