Added conditional logic

Adding conditions to survey questions allows for advanced survey logic, such as branching and skip logic. This means that certain questions will only be displayed based on the responses to previous questions. This can make surveys more dynamic and tailored to the respondent's answers, improving the user experience and the quality of the data collected.

Key Concepts
1.     Conditional Logic:
1.1.  Conditional logic determines whether a question should be shown or hidden based on the respondent's previous answers.
1.2.  Conditions are typically expressed as Boolean (e.g., true or false).
2.     Branching:
2.1.  Branching allows the survey to follow different paths based on the respondent's answers.
2.2.  For example, if a respondent answers "yes" to a question about owning a car, they might be asked follow-up questions about their car. If they answer "no," those questions would be skipped.
3.     Skip Logic:
3.1.  Skip logic is a type of conditional logic where certain questions are skipped based on previous answers.
3.2.  This helps in avoiding irrelevant questions and reduces the length of the survey for the respondent.
