Detailed Description

Basic test of FlowBalloonModel.

This test configures a FlowBalloonModel with parameters and functions set according to the first experiment in Buxton et al. (1998). Results are output on stdout, tab delimited, with columns representing:

; time
$f_{in}(t)$
$f_{out}(t)$
$CMRO_2(t) = \frac{E(t)}{E_0}f_{in}(t)$ (Buxton et al. 2004).
; BOLD response (%)

Results are as follows:
