Remove gth_solve.jl
Add gth_solve to mc_tools.jl
Add gth_solve to mc_tools.jl
Cleaned up QuantEcon.jl
mc_compute_stationary add option for sol'n method
Don't need to check dimensions since already checked in MarkovChain()
More compact looping in gth_solve
Refined mc_sample_path\!
Enforce consistent p transposition across solve methods
Enforce consistent p transposition across solve methods
Remove line used for debugging
Fixed line 100
x[n] to x[end]
Removed test_gth_solve.jl
Removed test_gth_solve.jl from runtests.jl
added kmr tests for test_mc_tools.jl
Fixed missing variable
tweaking settings for the kmr matrices, I think everything is working fine
Dropped  from P6 as it is exact
removed irrelevant comment
