Three different schemes for evolving linear hyperbolic systems in 1d:

lin_sys_LW_charlim.src : Does Lax-Wendroff timestepping of several different
linear hyperbolic systems. Can choose different CFLs with "mu" and different
limiters with "islope". Output in "rhoa0001" can be plotted with 
"onedplot3.pro". 

lin_sys_PC_charlim.src : Does Predictor-Corrector timestepping of several
linear hyperbolic systems. Can choose different CFLs with "mu" and different
limiters with "islope". Output in "rhoa0001" can be plotted with 
"onedplot3.pro".

lin_sys_RK_charlim.src : Does Runge-Kutta timestepping of several
linear hyperbolic systems. Can choose different CFLs with "mu" and different
limiters with "islope". Limit on characteristic variables or componentwise
with "icharlim". Choose modified Euler or improved Euler Runge-Kutta
schemes with "modified_euler". Output in "rhoa0001" can be plotted with
"onedplot3.pro".
