Restructured project and implemented virtual python environments to isolate application. Added launch scripts too.

+Standardized Comparison Node:
+  - Compares two input values using a selected operator (==, !=, >, <, >=, <=).
+  - Outputs a result of 1 (True) or 0 (False).
+  - Uses a global update timer for processing.
+  - Supports an additional 'Input Type' dropdown to choose between 'Number' and 'String'.
