Various C utilities I use to make writing programs nicer.

• strtonum : converts string to long long

• humanize_number : this allows you to convert numbers to human readable numbers.

    ex. 90000 -> 90K
  

• xmalloc : object checking for malloc, calloc, realloc, strdup, asprintf. It will exit the program is the function failed to allocate the memory needed.

• progressmeter : a nice progress message for file operations
