/* This code was taken from a program I wrote some time ago. It parses a string
 * for whitespace and quotes much like a shell would. Characters enclosed in
 * quotes are counted as a single token. Extra whitespace at the beginning and
 * end of the string is removed. The tokenizing function returns a token
 * structure, which can be used to access the tokens in the original string
 * (which will have been modified). Once the tokens have been used by the
 * caller, the token structure must be destroyed to free the token pointers. */
