parameters deep in source code

[Jintram]

e.g. drawTime function in 3DRadInf function has following lines to straddle time:

Real low(1e-100);
Real high(100);

(..)

const gsl_root_fsolver_type* solverType(gsl_root_fsolver_brent);
gsl_root_fsolver* solver(gsl_root_fsolver_alloc(solverType));
gsl_root_fsolver_set(solver, &F, low, high);

const unsigned int maxIter(100);

unsigned int i(0);
for (;;)
{
    gsl_root_fsolver_iterate(solver);

    low = gsl_root_fsolver_x_lower(solver);
    high = gsl_root_fsolver_x_upper(solver);
    int status(gsl_root_test_interval(low, high, 1e-18, 1e-12));

That "low" and "high" parameter should perhaps be re-allocated to hpp file, since they're dependent on the scale we're looking at.

(Put it in issue tracker to remember to look at this in general. Didn't fix it as it works for now.)
