README for "yomama" plugin.

It is to be used with the esh shell.  

It is a built-in plug-in type.

It is initialized with the "./esh -p plugins" call.

When you type in "yomama" the shell outputs a random 
joke as a message.

When you type in "yomama [int 1-10]" the shell outputs
a specific joke.  

If the user inputs an integer that is not between 1 and
10 or does not input an integer at all, then the plugin
will exit back to the shell and show the proper usage 
of the plugin as a message.
