Add a GridSpan()

[gowerc]

Would be good to have a grid function that provides N evenly spaced timepoints between each subjects first and last observation e.g.

subject_1 = seq(min(time_for_pt_1) , max(time_for_pt_1) , length.out = 100)
subject_2 = seq(min(time_for_pt_2) , max(time_for_pt_2) , length.out = 100)

I'm not really sure what to call it though. Am currently thinking GridSpan() but this isn't really that descriptive. Perhaps GridWithin() or GridWithinSubject() or GridSpanSubject()

GridRange, GridSeq?

GridEven() / GridIndividual() / GridSubject() ?

all ok for me - you can choose what is most congruent with the other names
