(MOD) Implemented Array_Create, Array_CopyOf and Array_Delete
(MOD) Replaced project compiler from "gcc" with "clang" due to out-of-order execution keep happening after running with Array. (MOD) Removed certain functions from Utils due to insufficiencies of usage. (MOD) Defined 1 more macro "fail". (MOD) Fixed 1 bug from "var.c": Struct member "alive" was not under supervision from the entire programme cycle. (MOD) Removed 1 useless usage for "Utils_LiteraliseInteger". (MOD) Removed 1 useless block of commented code.
