uwerr missing
dof not reading length

indexes permuted in output read_ms
comp_t0 fixes rwf, plot plateau added, L mandatory

read_rw included. read_rw reads ms1.dat and pbp.dat

doc updated + minor redefinition

input xdata Array{Real}

read_ms now returns YData
comp_t0 computes t0 R!=1 + rwf

Computes matching in the charm sector 
Scaling + chiral extrapolations are missing

functions returns uwreal not a Vector{uwreal}
