Check the template fits in the segment
We should have a test that the CBC signal we're using as the template actually fits within the segment we're using.
There may be lalsimulation functions to test this. I'll have a look if no-one else wants to.
We could either do this when we start sampling by testing the prior or do it at each sample point if it isn't going to be too expensive.
@rory-smith @paul-lasky @gregory.ashton any thoughts?
