update version 0.6 and roadmap

README.md

 HeLaZ (Hermite-Laguerre Z-pinch solver, 2020)
+Current version : 0.6
 
 Roadmap :
 
 0. Write MOLI matlab solver in Fortran using Monli1D as starting point
 
-	0.1 go from 1D space to 2D fourier and from Hermite basis to Hermite-Laguerre basis
+	0.0 go from 1D space to 2D fourier and from Hermite basis to Hermite-Laguerre basis
 
-	0.2 implement linear Poisson equation in fourier space
+	0.1 implement linear Poisson equation in fourier space
 
-	0.3 implement moment hierarchy linear terms
+	0.2 implement moment hierarchy linear terms
 
-	0.4 RK4 time solver
+	0.3 RK4 time solver
 
-	0.5 Benchmark with MOLI matlab results for Z-pinch (cf. kz_linear script)
-		Note : benchmark.m points out differences between MOLI and HeLaZ 
-		       in extremely simple cases as P=J=2, eta_X = 0 except one.
+	0.4 Benchmark with MOLI matlab results for Z-pinch (cf. kz_linear script)
+		Note : benchmark_*.m compares MOLI and HeLaZ linear results
 
-	0.6 Load COSOlver matrices <- Current stage
+	0.5 Load COSOlver matrices
 
-1. Implementation of the non linear Poisson brackets term  
+	0.6 Benchmarks now include Dougherty, Lenard-Bernstein and Full Coulomb collision operators
+	    Note : for full Coulomb, one must store a precomputed matrix from COSOlver in the iCa folder
+
+1. Implementation of the non linear Poisson brackets term 
+
+	1.0 use MKL FFT library and Orzag rule to compute the convolution in the non linear term as a product
