* While reading various files in the repo, just going ahead to clean up some typos (for clarity of text). * When calling `realloc()`, let the pointer be returned to the first byte of the memory block after resize. Compiler warns against not doing this too. * In addition, rename the file uitls.c to "utils.c" which seems to be the correct name in this case. NOTE: I recompiled and tested the `./pocket` intepreter and it still works as expected.
