Added minor nit/suggestion

README.md line 140:

> 138: | `--header-class-name <name>`                                 | name of the generated header class. If this option is not specified, then header class name is derived from the header file name. For example, class "foo_h" for header "foo.h". |
> 139: | `-t, --target-package <package>`                             | target package name for the generated classes. If this option is not specified, then unnamed package is used.  |
> 140: | `-I, --include-dir <dir>`                                    | add directory to the end of the list of include search paths |

Suggestion:

| `-I, --include-dir <dir>`                                    | append directory to the include search paths. Include search paths are searched in order. For example, if `-I foo -I bar` is specified, header files will be searched in "foo" first, then (if nothing is found) in "bar".|
