Add an additional formatter class RecursiveDecentFormatter which prints the

value and the decendents.  For an example,

rdf = lldbutil.RecursiveDecentFormatter(indent_child=2)
print rdf.format(g_table)

produces:

(const char **[2]) g_table = 0x00000001055a80f0 (location)
  (const char **) [0] = 0x00000001055a8080
    (const char *) *[0] = "Sunday"
  (const char **) [1] = 0x00000001055a80c0
    (const char *) *[1] = "Monday"
