[Click] Trying to install new element

[Fran]

The MMARPWaitRandom element is part of an implementation of the MMARP 
multicast routing protocol for Ad Hoc network which I have implemented. If 
you only want to use the element, you don't need the rest of the 
implementation. You have to modify the file and erase that line because the 
mmarp.hh is not needed.

         Fran.
