Correlation function & LMIN/LMAX

[elisachisari]

FFTlog implementation for correlation function implies that the comparison to the benchmark can only be done in certain range of angular scales. If LMIN>2 or LMAX<3e4, the code ccl_test_corr would crash because gel would attempt to extrapolate the CCL correlation to the range of the benchmark. To avoid this, I implemented a temporary fix by requesting that the correlation only be compared to the benchmarks in the range of the FFTlog output. This needs to be revisited later on.

This issue had to do with the integration limits of the Cells in the case of CCL vs the benchmarks. The implementation has changed significantly and we now find agreement between CCL and benchmarks within required accuracy, so this issue no longer applies.
