[sage-support] indicator functions

Hello, I'm looking at convolution products of Lebesgue integrable functions, and to get a better visualization, I want to compute some convolutions of indicator functions. So, want to have a function f:R->R defined by f(x)=1 when x \in [0,1], f(x)=0 when x \notin [0,1], and, I need the function
