Function: inspiral_dist()
void inspiral_dist(double *deff, double *z, double *Vc, double m1_z,
double m2_z, double snr, double S_h[], int npoint,
double srate, double h100)
This function computes the effective distance to which a binary
inspiral with redshifted masses m1_z and m2_z can be
seen with the noise spectrum S_h[].
It uses the energy spectrum

(6.33.157) 
to describe the inspiral for frequencies
,
and zero above (as in reference [13]).
To convert from luminosity distance to redshift, it assumes a universe
flat cosmology (, ) with a Hubble constant
, and uses an Eq. (11) from
[18]. To convert from redshift to comoving volume, it
uses Eq. (27) of [19] or Eq. (2.56) with of
[20].
The arguments to the function are:
 deff: Output. The effective distance in megaparsecs.
 z: Output. Redshift corresponding that effective distance.
 Vc: Output. Comoving volume at the redshift in cubic
megaparsecs.
 m1_z: Input. Redshifted mass one, .
 m2_z: Input. Redshifted mass two, .
 snr: Input. The signaltonoise ratio at which the
effective distance is deff.
 S_h: Input. The spectral density of noise in Hz.
 npoint: Input. The number of data points in S_h.
 srate: Input. The sampling rate used to construct the
noise spectrum, Hz.
 h100: Input. The Hubble constant in units of 100 km/sec/Mpc.
