Correlations

[aguinot]

Implement a module to handle the computation of correlations with TreeCorr.

Features:

• Read parameters from config
• Run shear-shear correlations
• Run count-count correlations
• Run count-shear correlations
• Make patches
  • Possibility to use already existing patches
• Can run in low_mem mode
• Save results
  • Also save covariance matrix
• Run using MPI (that would need to refactor the library..)
• Be as memory efficient as possible

In its current implementation this code is not meant to be called outside of an higher level class like rho_stat or alpha_leakage. This will need to be improved.
