Input configuration file

The input file is a .yml with the following structure:

If you set end_day and duration, duration will be ignored
If the name of bands in the db file doesn't match sncosmo bands you can use the key band_dic to translate filters names
If you use sub_field you have to define a representation of your sub_field in a txt file.
If you don't set the filter name item in nep_cut, the cut apply to all the band
For wavelength dependent model, nomanclature follow arXiv:1209.2482 -> 'G10' for Guy et al. 2010 model, 'C11' or 'C11_0' for Chotard et al. model with correlation between U' and U = 0, 'C11_1' for Cor(U',U) = 1 and 'C11_2' for Cor(U',U) = -1
Note that the FWHMeff in survey file follow LSST OpSim format and is equal to 2 * sqrt(2 * ln(2)) * sig_psf
mw_dust available models are CCM89, OD94 and F99 (cf sncosmo documentation)
