Cost of administration for an intravenous treatment

1 2	cost_iv_administration(iv_time, cost_first_unit, cost_addl_units, prorate_first = FALSE)

`iv_time`	The infusion time, in units compatible with the costs
`cost_first_unit`	cost for the first time unit
`cost_addl_units`	cost for the second time unit
`prorate_first`	can we charge for less than 1 unit of time? See details.

Simple formula: cost for the first time unit (prorated if total time is less than one unit and prorate_first == TRUE) plus the prorated cost for additional units.

If prorate_first == FALSE, then the smallest time that can be charged is one time unit. For example, if time = 0.5 and prorate_first == TRUE, the function will charge for one half of a time unit. If time = 0.5 and prorate_first == FALSE, the function will charge for a full time unit.
