Implement a fixed offset in r(par)
Make dpi a floating parameter defined in AbsCorrelationModel
added radiation effects for cross-correlations
Add a private method _applyVelocityShift to AbsCorrelationModel that performs a shift, including the conversion from dv to dpi using a fiducial cosmology.
Move from dpi to delta-v, using fiducial cosmology to convert using bin z value. Move shift code out of CorrelationFitter.
Define a second set of linear bias parameters if requested, to support cross correlation fits.
Add a cross-correlation cmd-line parameter
Pass cmd-line cross-correlation param down to AbsCorrelationModel ctor
Change params for second component from beta2 and (1+beta2)*bias2 to bias2 and beta2*bias2
Add INI file for cross correlation P(k) fit
Use second set of RSD parameters for cross correlation normalizations
Rework cross-correlation linear bias parameterization so that redshift evolution is applied to betaAvg and betaProd and biasSq can be negative.
Update cross correlation INI files
Merge remote-tracking branch 'andreu/cross_correlation' into Cross_correlations
Fix typo and replace std::pow(x,2) with x*x for efficiency
Move cross.ini to cross_xi.ini and create a new cross.ini for the cosmology fit
Rename radiation parameters for easier name globbing. By default, params are fixed.
Only define dv for cross-correlation fits
Float isotropic BAO scale in cross fit
* Generalize linear-bias model in AbsCorrelationModel to work for cross correlations
* Add fit parameter for radial velocity shift to allow for systematic errors in redshift
* Include Andreu's quasar radiation model in BaoCorrelationModel
