Array/Multi-array Support

[DavidBakerEffendi]

Added

• Support for multi-array creation added
• Array tests derived from JavaSrc2Cpg included

Fixed

• Fixed access path issue where array index accesses were reported to be invalid ASTs. This was just a change in AST children's order from (0, 1) to (1, 2)
• Fixed bug where if a single file was specified then all files in the directory were loaded

Changed

• Updated frontend to leverage Call(<operator>.arrayInitializer) instead of Unknown(new) vertices
