Dear Math Group,

How can I get the linear independent subset of a list of symbol, function, and 
derivative of functions?

Here is a example:
   For {a, b, a+b, c, b-c},  one of the subsets is {a,b,c}. In fact, any one of 
the subsets would work for me.

   Another example. For {F[x], G[x], D[F,x],D[G,x,2], F[x]+D[F,x], 
D[G,x,2]+D[F,x]+F[x]}, the subset would be {F[x], G[x], D[F,x],D[G,x,2]}.

I have went through the help of Mathematica and did find anything like this. 
Help is really appreciated.
